Well, see, there now you are wrong. Your itty bitty little dagger has missed its mark. For society as a whole has been harmed. For all of the "freedom" that people have nowadays to enter into depravity has led to a decline in society. STD's, unwed mothers, babies in trash cans, rape, child molestation, murder, drugs, homelessness, starvation, uneducated people, truancy...all these things are blights on society- they make it worse.
Now I am not saying that homosexuals caused all these things. But what I am saying is that the more immoral behavior is allowed to become mainstream (gays, premarital sex, promiscuity, drug use, alcoholism as a disease, etc.) and our standards of conduct are out the window due to supposed freedom, the more the nuclear family, and by that I don't mean the radioactive kind, disappears the worse society as a whole becomes. For the strength of our society there has to be morality- and, yes, that morality has real life, immediate consequences- see above.
And there is nothing of "whims" in our belief that homosexuality and thus marriage of homos. is wrong....it's been that way for 1000's of years...that's not exactly what I'd call whims it's what I'd call historically significant.
