Some of them do have a larger reach, but many others do not and are just everyday people, and most of those with reach generally built it from nothing. And regardless of what algorithms put in front of them these people are often directly courting the attacks by quote tweeting and replying to the chuds they come across.

I do not believe the odds uniquely overwhelm most people in the way you describe, and the ones that are so overwhelmed of course can totally disengage to preserve their well being. But I hope that most of us are not disengaging permanently, and find some sort of inner resolve that can steel us against inflammatory rhetoric enough to articulate cogent and unyielding responses at least on some days.

Like, I stopped reading Twitter, but I still reply when an Instagram/YouTube comment I come across is hateful or ignorant to lay out what the commenter is overlooking, even at times when that comment already has a ton of likes. And even when I leave a mean response to the ignorant or hateful person, I don't forget to also leave positive and sincere praise for the person being attacked or a similarly marginalized person. I think that's something most of us forget to do when we are too focused on countering incoming attacks, not focusing enough on putting more positivity out there.
