I don’t care what she said, it is not the job of private businesses to censor elected officials. And yes, I know they can but that does not mean they should .
So you're saying no elected official should be bound by any laws, contracts or the terms of service of any organization, since doing so could be interpreted as "censorship?" That if anyone else had said what Marjorie Taylor Greene had said, they would be subject to action by Twitter under its own stated policies, but the rules just shouldn't apply to her?
When people say "hang the rich" on Twitter do you see them getting banned? Twitter specifically says they do not accept appeal to violence, but in reality they only censor the language they don't agree with.
