Gay pride days? Gay pride parades? Homo awareness? All that sh*t should be kept out of the public.
None of that really has much to do with wanting to get married. Parading and campaigning about the issue, perhaps. But the actual act of marrying one another really has little do with you if you have nothing to do with the people involved.
Oh, and yes, it certainly IS a choice.
I said CONSCIOUS choice. I can't think of a single gay person who I either know personally or have ever heard of who one day woke up and said, "you know what? I'm doing with being straight, I'll give being gay a try."
