It's certainly not impossible... it just takes more moderation, and that mean's more mods... we have 4 mods for a community of thousands.
I am on plenty of forums, drug related... where most everyone is friendly and respectful, if you're not... you're warned, and then banned.
And I agree, misunderstandings happen in real life... but when they do, usually apologies are made... just as they should be on here.
As for calling someone a bitch ass punk for saying bitch ass punk things... that just shows a lack of maturity on the part of the person calling the other a bitch ass punk, there are better words to describe "bitch ass punk things"...
