You don't see the relevance because the analogy makes no sense.
Homosexuals aren't victims because they are homosexuals. They are victims of screwed up genes. There's no fixing it either. Validating the screwed up sexual orientation by pretending that it ISN'T screwed up isn't going to fix it. Soceity shouldn't be forced to say something is normal when it's not. That doesn't make society a victimizer. It's just common sense.
Bottom line: Every society has the right to decide on the parameters of what consistutes a marriage. Heck, there are strict rules on who can DRIVE.
Something as profoundly important as marriage deserves a society's best efforts. Opening the doors to SAME-SEX marriage would open the door to polygamy, woman marrying multiple men, child marriage and Farsi marriages (anything goes but monther-son marrriage). Even the most foolish moron in the society knows that changing our laws on marriage would be opening Pandora's Box -- moral chaos would ensue.
Follow-through on the thinking:
For all the Muslim lovers out there, THEY would be the next in line asking for polygamy. We would then have to give it to them. The Mormons would rejoice. All those guys could get themselves a younger wife every two years. They could pretend to be Biblical patriarchs or harem collectors of Arab lore. How lovely for our women and all those children.
Homosexuals are abnormal. They DESPERATELY want society's validation that they are normal. "Marriage" is a validation of their profound abnormality.
SAME-SEX marriage is just wrong. Very simple.

There is no genetic component to Same-sex attraction disorder. Lots of studies have reported finding a link and all of them have been bedunked. It is entirely a mental illness.
It is caused by one of three primary causes. 1. Having a weak or absent relationship with one's father, 2. Being molested or abused. 3. Being relentlessly teased by one's peers during the formative years.
It is also curable. Reparative therapy, oth secular and religious has shown a cure rate at least equal to the cure rate for alcoholism. There are thousands of ex-homosexuals.
