By saying some thing is Gay and mean it is Bad Stupid Crap , The list goes on, is implying that you think that homosexualty is that same.
Which means you are a homophobic , and you believe Homosexuals do not belong within our Community, which is raciest to say the least.
Thats wrong, i do believe everyone should have their opinion, but some should not express in such ways, how about using other words to fill that gap, and be more courtesy to other people.
To sum it up, you can say what you want, its a free world, freedom of speech and all, you should be careful of what words you choose, because you dont know what kind of company you will be with.
