Over the weekend, the Wall Street Journal reported that "President Trump is considering establishing a panel to review complaints of anti-conservative bias on social media." That story is likely behind a paywall, though Fox News (natch)

The basis is exactly what you think it is. A bunch of Trump supporters have been falsely insisting that social media companies are unfairly "biased" against conservatives. There is exactly zero evidence to date to support this. There are a few anecdotes of whiny assholes, who violated terms of service, losing service, and a few anecdotes of just not very good content moderation (though, those seem to fall pretty broadly across the political spectrum). There is no indication that any of the moderation activity is unfairly targeting conservatives or even that there is any "bias" at all. I'm sure some people will rush to the comments here with one of two reactions: they will either call me "blind" and complain that I'm simply not looking around (though they will present no actual evidence) or they will cite a few meaningless anecdotes, ignoring that a few anecdotes on platforms that have to make literally millions of moderation choices, is not evidence of bias.
