This isn't offense particularly, but outside of spouting the usual self-righteous wank (which I and everyone else already agrees with), there's not much else to say on the topic of censorship in broad.
I'm a fan of reading feminist discussions (because I'm a boring twat), the arguments surrounding sex positive vs. sex negative, how to establish sex-workers rights without becoming too much of a nannying curse over a lady's body, writing Angela Carter fanfic - all that.
Buuuutttttt.....
Finding an active community with some deep discourse and well-written Bloody Chamber-slash-Firefly prose is nearly impossible without heavily curating the comments which are allowed to be posted. If you open the floodgates you're almost immediately inundated with "YOU'RE A WHORE" and "Hi, ladies, I was hoping to have a polite discussion about why YOU'RE A WHORE

" messages. People who are there only to argue about how massive their totes rational e-boners are ruin any chance of actually having a meaningful discussion - you're constantly having to defend why you should be having the discussion in the first place. It's a real shitter. It's the same, which less vitriol, for pretty much any academic topic - unless you aggressively dump the garbage your well-meaning science forum is going to be filled with 'Guys, I got stoned and totally hi-po-toe-size that quantum mechanics is the solution to everything' and 'Scientists discovered the cure for AIDS for the eight time this week.'
Getting rid of them usually leads to cries of censorship and how feminists totally can't handle their 'But why aren't """"womyn"""" on the draft, huh?' and 'Why don't you just call yourself humanists? *smug face*' logic-bombs, but fuck em. I'd much rather censor then have to argue feminism 101 with yet another bad-faith douche who refuses to listen to anything but 'You're totally right - Anita Sarkeesian is a lie.'
