[how does allowing gays to get married harm you, if you are straight?]

Because allowing gay people to get married would be the same as allowing pedophiles to marry children. After all, why shouldn't pedophiles be allowed to marry what they are attracted to? They can't help it, after all!

[Fool, how is a child a consenting adult?]

Your logic sucks. The point is that at some point, you have to define what is actual marriage and what is unadulterated perversion. Why can't people who are addicted to beastiality marry farm animals? The lunacy has to end at some point.

Oh and by the way, God makes it clear in the bible that homosexual behavior is wrong, and that people who encourage the behavior will be sent to hell along with them(just read the story of Sodom and Gamorrah.) So in that way it affects me very greatly. Of course, you probably don't believe in God, so this last point is lost on you.

[UT OH!! He pulled the his trump card!! The bible says it!! Come on man, not fair.]

Ok then, I'll give you another argument that has nothing to do with my belief in God:

In the United States, a little over one million people are infected with HIV. Of these people, 75% are gay/bisexual men who acquired their infections through sex with another man.

So basically, the male homosexual population is responsible for the vast majority of the HIV/AIDS problem in the United States. Thanks, but no thanks.
