Fear that gay people will become as promiscuous as the Mormons reputedly are, thus shutting down the sanctity of the entire institution of marriage, the latter being strongly tied to religious reasoning (though religion itself should not be to blame; people of all walks support the Faith and none should be disrespected for it)
Also fear that your friend might actually be happier kicking it with some sweet, awesome guy instead of saying smack about that one girl whom your group of friends talks about as if she were a slut. Goodness forbid your friend should be happier being in love with a man instead of trying to get in her pants.
Don't hate. Remember the Civil Rights Movement? Remember the struggles blacks went through so they wouldn't be disrespected anymore in public? This is the exact same thing. Remember the discrimination post-911 that Muslims went through in the US? Was that just? No. Just because "fag", "nigga", and "a-rab" are popularized terms, doesn't make them right.
"Dude, I told my little bro not to be a fag, and he told me I had a case of hemophobia."
"I think he meant homophobia, and dude, he's right."
The sensation of falling off the Golden Gate Bridge every single day.
...I sincerely pray that I never wake up to find myself doing it in real life...
