There was literally zero racist activity on The_Donald. The mods were very transparent and showed EVERY ACTION once they hit quarantine (to show they didn't deserve to be quarantined). The only racist posts came from new accounts / people who had never posted in The_Donald that were immediately removed by mods.
At this point been pro-Trump isn't really an ideology, it's a cult in all but name.
I've got conservative friends (UK style conservatism), I disagree with them but I can respect their beliefs because I can see how through a different lens I could hold their views, for the pro-Trump folks that lens just gets further and further away.
At this point I'm not sure what Trump could actually do that would surprise me - I mean I'm old enough to remember people mocking Bush for doing/saying the odd dumb thing but Trump went full-idiocracy inside 4 years.
I dislike these things as well. Where exactly do you hangout? Because if you meant 4chan, it's hard to have a meaningful conversation there.
