It was the balls:

    If a trans-identified male is in a female-only space, 
    he is committing a violent, abusive act. Make a scene, 
    call the cops and if all else fails, punch him in the 
    balls.

By inference he thinks that if someone makes you feel uncomfortable, by doing nothing illegal nor immoral (in the mind of a right-thinking person), punching their genitalia is acceptable. If I ever meet him I think I might feel quite uncomfortable, which would be unfortunate.

I'm not actually. How did you get "arrested for tweets" from my post where I said it was a video of a 20-something year old having a debate with someone at a pub?

I'll take that as confirmation that it happens all the time though - since this was evidently not an isolated case, as you have pointed out.

Unpopular opinion: your right to free speech includes the right to advocate for violence, so long as it's not imminent (as in inciting a riot).

That includes your right to support Hamas or Israel, your right to support abortion, your right to support defensive gun use, your right... well actually your right to support a lot of things given how readily innocuous things are described by opponents as "violence" or "assault".

Fortunately in the U.S. this is recognized under Brandenburg v. Ohio.
