While I don't think your position on free speech is unreasonable, to overlook the harmful things the right is doing and base your vote on Twitter's moderation policies seems like cutting off your nose to spite your face. Off the top of my head:
* Don't say gay bill * Huge restrictions on abortions that have been enacted recently and will undoubtedly be upheld by the SCOTUS. Even in cases of rape and incest. * Gerrymandering, ensuring the right will stay in control even if they are not supported by the electorate. * Restrictions placed on voting that target minorities
I also think phrasing this as crushing political dissent is a gross exaggeration. We're talking about very extreme people being suspended from a social media website. No one is getting arrested. If you want to see examples of people being arrested, look at Texas where a woman was recently arrested for suspicion of having an abortion, or Florida where Desantis had a researcher arrested for releasing COVID data.
