Really, never heard of that.
I remember a long time ago when I was listening to a campus radio station and there was this gay show and the person was coming up with a list of quintessentially gay stuff like disco. Yet when some dude who does not love the smooth taste of cock points out that something is gay suddenly he is homophobic. I call bullshit.
Liking the royals isn't gay because it sucks, it is gay because it is gay, much like dancing, musicals, disco etc. OTOH calling Chemistry or the Simpsons gay could be considered a homophobic use of the term, for those people who are too stupid to understand that words can have multiple meanings, why I remember this one gay old time I had sucking back on a fag.
As for my comment. How the fuck is calling a dude having a celebrity obsession with another dude gay homophobic. That is a bit like when MC Vagina called someone a racist because they said you can't spell chorus with vagina.
Also if you can't tell the difference between being opposed to gay marriage and thinking something is gay... fuck dude I don't even know where to begin.
