I mean, he's kinda right though. Dems are known for suppressing free speech. Look at lemmy, it's 99.9% blue and you once say something like "Trump gud, illegal immigrant Kamala bad" and instead of a factual argument with a birth certificate attached, you just get a ban.
Dems want an oppressive regimen where everyone who disagrees with them is silenced. So, I understand why he's worried.
And if this does happen, you'll see lemmy cheer. Lemmy values free speech and independent opinion only when it aligns with their.
