Even though English isn't my native language I'm fully aware of the definition of rude, thanks for the dictionary suggestion, I'll pass though.
As you can read yourself in the post you're quoting, they're clearly making a distinction between forced sex and rape, because otherwise they'd just either ban "rape" or generalize by banning the description "forced sex". If it means the same they'd use one of the two, not both for no reason if they're the same thing. Now, if they're making a distinction it goes without saying they meant it to mean different things. Notice they aren't saying "bestiality" and then adding "sex with animals"...
Also I've been having sex for 20 some years and am part of actual BDSM communities I know what is vanilla and what isn't, you can trust me on that one. Being rough isn't the same as being kinky. Just being rough is being vanilla, only less boring. If one day you have sex yourself sometime, I'm sure you will be able to tell the difference.
Now here's the rude part of your post "Being ok with the first one and not with the last one makes no sense." you're calling them out for being ok with forced animations, which by the way the original is phrased "forced sex, bestiality or rape" doesn't seem to intend to mean the same as rape. But you saying it means the same thing are just calling them out for being ok with rape. Which they aren't and that's a horrible thing to accuse someone of. If you don't think this is kinda rude, how about just generally shitty? Come on, there's really no need for that triggered, holier than thou bs here, we're all adults (I hope lol) relax..
I didn't mean to continue to engage, I won't clutter this thread anymore with chit chat and I apologize for doing so with this post.
Edit: oh forgot to add, Grey Naya's "The Obsession" animation is forced but you can see the bottom is enjoying it. It's the perfect example. Sexuality is complex, there's situations and relationships in which the same action will be received differently and have completely different results.
