First of all, it's incredibly ironic and somewhat hilarious when thought about the way gays react to the f*g word. The intolerance, and general prissy repulsion towards the word by gays, is exactly what the f*g word is describing.
People are allowed to say all sorts of things, retard, stupid, gay, straight, homophobe, white, black, etc. Anything can be offensive to anyone, if one doesn't respect others' rights to freedom of speech then he or she deserves none as well. Which if I am banned, it's ironic. I'd be Hitler-like banned for using my freedom of speech by the same people who Hitler would have banned from using freedom of speech.
