The cause of this riot was not Tulsa. It might have happened anywhere for the Negro is not the same man he was thirty years ago when he was content to plod along his own road accepting the white man as his benefactor. But the years have passed and the Negro has been educated and the race papers have spread the thought of race equality.
What part of this paragpraph are you having a hard time with?
"The massacre began during Memorial Day weekend after 19-year-old Dick Rowland, a black shoeshiner, was accused of assaulting Sarah Page, a white 21-year-old elevator operator in the nearby Drexel Building.[25] He was arrested and rumors spread that he was to be lynched. Several hundred white residents assembled outside the courthouse, appearing to have the makings of a lynch mob. A group of approximately 50–60 black men, armed with rifles and shotguns, arrived at the jail to support the sheriff and his deputies in defending Rowland from the mob. Having seen the armed black men, some of the whites who had been at the courthouse went home for their own guns. There are conflicting reports about the exact time and nature of the incident, or incidents, that immediately precipitated the massacre.
According to the 2001 Commission, "As the black men were leaving, a white man attempted to disarm a tall, African American World War I veteran. A struggle ensued, and a shot rang out." Then, according to the sheriff, "all hell broke loose."[26] The two groups shot at each other until midnight when the group of black men was greatly outnumbered and forced to retreat to Greenwood."
Instead, you assert it was a mob that assembled to lynch a young man who was arrested for assault after he stepped on the foot of or grabbed the arm of a white female elevator operator when he tripped in the elevator. I guess they got out of hand when there was resistance to their murdering the kid.
Why is that distinction so important to you?
The black community resisted the lynching and stood up for the poor bastard they wanted to murder. Their prosperity as a community and individually gave them the fortitude to fight back.
It wasn’t “because they were rich”. It was because they had agency and dared to stand for their rights as a community. For a person who believes that the color of your skin makes you an inferior or superior human, that is an unforgivable affront.
It is very simple.
In the history of revolution, there is never (except in elementary school) all that much weight put on the singular act which instigated the final result. The conditions in place (Jim Crow laws, Southern pride, etc.) lead up to a final moment which our monkey brains like to point to as the cause but in reality there is a simmering cultural froth which could boil over in any number of ways: it just happens that one of the ways is what's described in the Wikipedia article, but it could have started many other ways. All of our understanding about the experience of being Black in the US during that time helps to contextualize the extreme and disproportionate outburst of violence by the White population as racially motivated, serving under an ideology best described as ur-"Great Replacement Theory".
In simpler words, the destruction of Black Wall Street is not without precedent, indeed this was merely one of the more famous and complete examples of destroying the wealth that Black people enjoyed, if only briefly due to the hate of those visiting violence upon them.
"Don't feed the trolls". They absolutely do know what they're doing.
Go read a book about it, and then if you still want to, you can tell us why this interpretation is wrong.
Racism is a complex phenomenon not limited to the simplistic view "they don't like black people". This representation is doing a disservice when some truly racist people are then justifying their actions and beliefs by saying "I cannot be racist, I'm friend with the garbage man who is black: he is a good black man, is polite to me and stay at his place. So, if I'm not racist, what I'm doing is just legitimate".
In the context of Tulsa, it is difficult to believe that the frustration of racist people seeing black people more successful than them has not contributed to the situation. It seems very natural and logical (and that's even the core of "white supremacy": it clearly states that white people deserve a better position in the social hierarchy than black people: white supremacy framing is all about how some classes are reserved to white people and not black people), and if you are claiming that it is not the case, you are the one with the burden of the proof.
While you have a point on raising that racism should not be reduced to only a class issue, you should have raised that as a precision around the discussion instead of presenting it as if racism has absolutely nothing to do with class and class sentiment.
To take back your parallel, what you do can be seen as: "A person entered a bar and was raped" (what you say) vs "A woman entered a bar and was raped". While nobody here claims that men cannot be raped, there is social phenomenon that create a gender imbalance, and it is important to not reduce the situation to "it has nothing to do with gender and the social norms around it".
In the rest of your comment, you, yourself, are doing a lot of interpretations. The fact that someone noticed that a class factor may have had an impact does not mean that they or all readers will conclude that it is the only way racism can happen (that is a huge stretch: if they know what happened at Tulsa, they very probably know a lot of other cases where the "only due to class" theory does not hold up). Same for "victim blaming": the fact that they were successful were obviously not used to excuse the massacre or pretend that somehow it was the black people's fault, the context is clearly to condemn the white racist people (and the success of the black people seems to be presented as an obvious additional factor on the racists, as it is obviously unfair to pretend that some people don't have the right to be successful).
I think the first comment was not totally perfect and would have been 100% fine if they would have simply added "class was one of the factor". But I think your reaction has way more problems and does a bigger disservice by reducing racism to a framework that can easily be instrumentalised by real racist people.
