Trump threatens to 'close' down social media platforms

I’m an outsider (not American, don’t live in America) so I’m almost not entitled to have an opinion on the matter, but it always strikes me as fairly odd when people of one persuasion or another rail against the ‘bias’ that they perceive against them in one circumstance or another (including media coverage).

Of course people see bias against them. It’s classical confirmation bias: every time something goes their way, it’s unremarkable, but as soon as something doesn’t, it’s noticeable.

Isn’t it equally possible —nay, probable even, especially in this case— that the perceived bias is only the prevailing opinion of the majority against whom one is in a minority?

This is basically true. Liberal or conservative, everybody I talk to who can communicate ideas without injecting vitriol into every word agrees that 90% of "censorship" of conservatives is just censorship of standard low-value hateful garbage, and that genre of speech, while committed on all sides, is highly overrepresented by conservatives, which makes life hard for the majority of conservatives who are rational.
