How can Twitter be the home of the left due to being an open and free space if open and free spaces are also supposed to be dominated by alt-right trolls that drown out the opposition through harassment and white noise? Don't people also frequently complain about Twitter's handling of harassment and the lack of moderation?
My favorite part is that he seems to be under the impression that Twitter just comes as a natural flow of information to you with powerful egalitarian debate happening before your eyes about the most important issues of the day. Not that you probably followed a bunch of people you know and like and can create your own echo chamber just as easily and then some idiot goes "let's do some game theory" and posts 50 tweets in a row, none of the replies to which you see unless you actually seek them out and none of which you actually read critically.
Any white man who wants to hold on to their prejudices and anxieties is going to have a tough time of it on Twitter
Unless, you know all they follow are these same YouTubers and dismiss or react to any criticism in the same manner as people do anywhere.
Or by say, blocking everyone they can track down with any association to a problem site.
