People are generally blind to the kind of stuff that get says on the internet unless they've been subjected to it personally. It's why the otherwise woke people get targeted by it and eat their own. They don't understand how the mob mentality works. It's perfectly fine to give criticism or condemn people's actions but when such things are magnified by the voices of millions the most extreme and violent positions end up spreading. It's no different than how political movements become radicalized, religions become radicalized. You are insulated and otherwise unaware of these troubling aspects as they are directed outwards until you find yourself as a member of the outgroup and targeted by it.

It's why it's vitally important to have a consistent self-established ideological base. And not fall blindly to the tautologies that infect popular discourse. Things are rarely as simple as a three word slogan.
