Yes, they have the right to ban whatever subject matter is being disseminated under whatever rationale. But to argue that this is simply them trying to prevent "false" information from being disseminated is, I think, missing the concern. If you don't think there isn't a ideological or political bias in their determinations then I have to disagree.
Social media sites saying that there is no verifiable evidence to support the allegations is not making a determination of what is true or false. The political aspect is that the allegations are being made for political reasons, not that social media does not want to be associated with them. Do you think that judges who throw out meritless Trump legal actions for lack of evidence are operating with political bias?
As far as the allegations about Trump not being suppressed, what allegations made without supporting evidence are you talking about? Allegations about Trump wrongdoing, such as Trump paying to cover up affairs, committing sexual assaults, and trying to get the Ukrainians to start an investigation into Joe Biden were based on evidence e.g. hard documents, actual victims and official transcripts of the President's calls.
And for what it's worth, I voted for Biden.
For what it's worth, I didn't. Congress passed a law that took away my vote - not because I am a convicted felon or anything like that, but merely because I am Canadian. How unfair is that?
