This sucks and there's no way to push back on that. First, if you do it too much, you're just a "reply guy" - you become a part of the same suckiness of social media that you're trying to push back against. Second, the near-universal reaction you get is "maybe these specific immigrants were not eating pets, but you gotta agree with my broader concern about immigration". This just an example, the reaction has its equivalent for all sides of the political spectrum. We just like to read stuff that aligns with our political identity and beliefs. The pursuit of truth is a distant second.
I think that for social networks or forums to be at least somewhat healthy, they need to be small, specifically to limit the interactions you have with complete strangers and content that doesn't interest you at all. If you open up the ecosystem too much, it devolves into some flavor of Facebook.
In this case, pumping around information so social networks appear to be one unified system is a good thing because you don't have to visit them all to check if there are new posts, etc. and you can avoid getting caught in an algorithm.
