This seems like obvious satire to make fun of the last 4 years of the Democrat party's obvious collusion with big tech to censor opposing thought.
Quite a few points here.
Let's start by simply taking Florida Republican's word that this was meant for nothing more than to 'showcase the absurdity of the left'. That in and of itself is a pretty stunning admission of just how unserious they are about governing. Their defense in this case is literally that they are drafting and submitting legislation for no other purpose than to "own the libs". Do they seriously have nothing better to do? You would think after all of that complaining about gas prices, inflation, deficits, etc. That they would have real, actual work to do.
I don't of course take their word seriously, because it's just plain stupid. Everyone who knows anything about politics knows that the Democratic party of the 1860's was the conservative party of those days and the republicans were the liberal party, they have since switched sides so the republicans of today are far more aligned with the democrats they are pretending this is about. Political parties are not people, they're entities. The people running them are a completely different group and the values pushed by it have evolved to the point of unrecognizability. To argue that this has any relevance to cancel culture only demonstrates what a moron the person making that argument is.
Third, Florida Republican's complaining about cancel culture is beyond hypocritical given what they just did to Disney. And that's just one example. We can talk about M&M's, Colin Kaepernick, every politician that's ever said a bad thing about Donald Trump... Republicans love cancel culture every bit as much as those they accuse of spearheading it.
Fourth, where are the condemnations of this? Where are those voices out there assuring the people that they don't actually plan to outlaw the Democratic party? Maybe I'm missing them. If you can find them please forward.
Fifth, your whole argument about big tech and censoring thought is just absurd and the Twitter files is a complete joke. This topic needs a whole other thread which I'm sure someone already started.
