This is absurd. Twitter etc are private companies and can do what they want wrt their user's accounts. If they don't want their far-right politicians getting censored, then they can ban those platforms from the country completely. As the saying goes, you can't have your cake and eat it too.
A restaurant is a private company and if they don't want to serve blacks and jews they can completely do it. You see now how absurd that argument is?
There was no state law against racial discrimination and the bar only used local products so didn’t engage in interstate commerce.
You see, unless we specifically make laws to protect a class of people, private companies will discriminate on that basis.
I guess the question here is do we want to make “people who lie and spread disinformation about important matters” into a protected class. As if is now, we barely discriminate against them. You have to lie for 4 solid months, culminating in a violent riot against the central government before any private entity will ban you.
