Parent has a point. You can find any manner of horrible on twitter, especially if you reach back far enough. Twitter is not a "primary source" in the wikipedia sense.
You could just as easily go and find 20 tweets from 2014 of women saying they refuse to date black men. If you build your worldview by cherry picking the opinions of 20 twitter users out of 300 million and treating them as gospel then you can create any bleak reality you want.
