"Freedom of speech is the ability to express your opinion, NOT the ability to say that your opinion is truth"
I don't believe in Insulting people, it is pointless. Sure, I have my oppinions about people, but the point of an oppinion is that it is YOUR oppinoin, not that of other peolple.
I see a girl and think "Meh, whatever" and somebody else think "DAMN that is a nice ass" and then says to me "Did you SEE that man? she was awesome hot bro!" I don't run up to the girl yelling "I DON'T THINK THAT YOU ARE GOOD LOOKING!" I simply say "Meh, nothin' special." to my friend.
No point in an insult whe silence can be kept. And anyway, I could go out on the streets yelling anything I wanted, but I don't because I have JUDGEMENT. Judgement is the key here, not limits.
