Basically, homophobes and those with bigoted views shouldn't be starting threads on civil rights issues--their fear-based prejudices prevent them from having any rational opinion or thoughts.
"The only argument" ... when you start of saying something that ignorant, it's as if you haven't been following the case at all and you understand nothing about the 14th amendment issues.
Perhaps you should read up on the legal issues, the real "arguments" made by both sides.
Good luck. And keep in mind, you can't catch homosexuality, you have to be born with it.
