Chad Thompson makes an interesting point about using social statistics to argue against homosexuality and same-sex marriage.  Even if it is true that the average homosexual only lives to age 43, or that homosexuals are much more likely to be highly promiscuous than heterosexuals, this may not be true of the homosexual you are speaking to.  They may be age 65 and engaged in long-term, monogamous same-sex relationships their whole life.

Additionally, such statistics do not necessarily show that homosexuality is bad or immoral.  What if homosexuals argued against the validity of heterosexual relationships and opposite-sex marriage on the basis that 43% of marriages end in divorce, and 3/10 women killed in this country die at the hands of their husband or boyfriend?  Would you be prepared to conclude that heterosexuality or marriage is immoral, or ought to be avoided?  Surely not![1]  So why think someone who believes homosexuality is morally and socially benign will be convinced by statistics showing the dark side of homosexuality?  They could always argue, as heterosexuals do, that while these statistics are alarming and cause for concern, the solution is not to condemn homosex but to encourage homosexuals to behave better.
