10) Americans have a strong sense of tradition. Even most atheists old enough to vote realize homosexual marriage is breaking a sacred tradition. 9) Homosexuals have zero chance of reproduction where as the elderly and the sterile had at one time a chance to reproduce.
8) Homosexuality is still widely viewed as a mental disorder. We wouldn't give the blind a driver's license, therefore we shall not give the gay a wedding license.
7) Marriage is a religiously owned tradition. The majority of Americans are religious.
6) Allowing homosexual marriage will lower the standards of marriage. What then? Polygamy? Child marriage? Animal marriage? Marrying an inanimate object?
5) Domestic violence is at its highest among gay men.
4) Emotional, psychological, and psychiatric disorders are highest among homosexuals.
3) Substance abuse is highest among homosexuals.
2) Sexually transmitted diseases are highest among gay men.
1) If homosexuals are granted full legal marriage their medicaid and medicare will be paid for out of increased employment taxes. Because HIV, substance abuse rehabilitation, counseling, and psychiatric medicines are expensive, the taxes will be huge.
Americans struggle hard enough already. The raise in taxes is an unrealistic expectation of hard working lower and middle class America.
End of story.
