It's pretty simple logic. One is a racial slur that really offends a huge portion of the population that has been persecuted for years. The other is a deragotory term used to emasculate men. It can be used to single out folks of a certain sexual preference, but it's most commonly used to emasculate men - even amongst their ranks. It's freely used amongst the gay and heterosexual community. The word has lost a lot of its venom through the past decade. Also, it's a cigarette.
It's not comparable, nor does it matter. So you don't get to use a racial slur. And you care because?

demi, I know you're a hermit, but people actually get pissed about it outside of the Internets.
