A lot more overt racism? You could always search "white people" and find plenty of dark and nasty things, including from very public people who get plenty of praise for it. Overt and celebrated racism has always had a home on Twitter, and if anything there seems to be somewhat less of it.
Well the question is, do you want a town square or do you want a gated community? Town squares have a lot of filth. To filter it out is to pretend that humanity is something that it isn’t.
You can filter it out in your own Twitter by following people you like.
Town squares have racists, hedonists, nihilists, globalists, misanthropists, moralists, pacifists, anarchists, theologists and everything else. The only new thing about this town square is that everyone has a megaphone. It’s up to you to find the crowd you want.
Some of the things you don’t tolerate are benign to others. And some of the things you like are cancerous to others.
