I have no problem with swearing or harsh language, Hivers behavior is pretty toxic tho, running around insulting people left and right, for no other reason than disagreeing with him, is not a socially acceptable behavior, especially when you cry "foul" when someone calls him out.
What he does is basically "You are not allowed to call me "xy", thats not an argument" and then 2 lines later "you are an idiot, i hope you get cancer". See the problem here? He just packs it in better sounding language, trying to fool people with it.
Basically he is doing everything he accuses others of and failing to see that makes it laughable or to put it in his words, makes him a simpleton. I spare you the repetition of his other more colorful descriptions. He is allowed to say those words, others not apparently. Quiet stupid, no?
Using many adjectives does not make one intelligent, it fools people into thinking that. Its a pretty common tactic.
He has some points that make sense, sure, since nothing is black and white in the world, and a forum is there to discuss it, but his failure to even acknowledge that there are other valid opinions, besides his own, thinking that he holds the absolute truth makes him the opposite of intelligent.
If you read his posts and replies carefully you can see that 90% is inflammatory language without any meaning, sometimes the replies do not even make any sense, or match the thing he replies to.
It seems that he is, on purpose, not understanding simple lines or has a problem comprehending, maybe that's why he is masking his replies in intelligent sounding, meaningless, insulting phrases.
Troll or not, lulz or not, its socially unacceptable behavior and goes against forum rules as others have pointed out.
Don't fall for it.
