Eeh, i don't mean it in a sense you put in. They're rough because they're literally rough to deal with, hence all usual: "You can't be rude, how dare you! Me? I'm not rude, i'm just telling the truth, i'm teaching how to be right!". It would be too simple if rude and rough people understood what they're doing, usually they're hypocrites that try to look nice and good.
Adapting to it means you understand that there are dummies here, that their opinion can be easily neglected, and that you suffer nothing for treating them as they treat you. I personally like it here exactly because hypocrisy and circlejerking doesn't help, you can give rude answers to people who hide rudeness behind looking good, and not get destroyed by "highly moral" moderators, since this place is for pirates and obviously doesn't try to look highly moral. Well, i didn't see anyone who did.
