I feel like before 2015 reddit was way more free speech focused. Now it seems like every sub will ban you because they don't like you politically or you violated rule 15b paragraph 2.
Basically every sub is run by tiny elons with a power trip.
Yeah if you have a politically different opinion you get banned for "Trolling" as if it's impossible for someone to genuinely believe something they disagree with. This is already happening on lemmy unfortunately
