i use it because it works well, saying "thats so gay" or "shut up f*g" just works so damn well. its really not my problem and i dont give a shit if you take that in the wrong way. if your stupid enough to think that me saying "thats gay" means that im actually referring to gay people or homosexuality as a bad thing then im fine with offending you. and if you are weak minded enough to let it get to you, then even more reason for me to not care.
I have nothing against gay people at all, i dont like dick and i like nothing about gay sex. but im all for people doing what they want in private, and some of my best friends are gay. and yes, i use these "homophobic slurs" around them all the time, and they are strong enough people to not care, shit they use it too.
Im so sick of all the PC dont offend anyone for anything, anti bullying bullshit out there. sorry but people will always offend you, and people are always going to have a problem with abnormality. being gay is not the norm, so naturally people are not going to treat you normally. everyone has their abnormalities, nobody is completely normal, people are always going to point out others differences, and nobody is going to like everyones differences. its human nature.
if you cant deal with the negative attention your differences bring you, then dont show them. if you are strong enough to rise above peoples criticism then go for it. let everyone know.
