That’s easy - because there’s nothing good about “same-sex marriage”.

Nothing?

To the degree that it cuts down on promiscuity and the spread of STD, it's "good".

I believe that is what is called 'damning with faint praise'...

Ha-ha-ha-ha-ha-ha.

You really think homosexual relationships are monogamous?

By institutionalizing a model of homosexual relationships that children will be taught at the youngest ages, homosexuality will be encouraged. More homosexuality in society is almost certain to increase promiscuity. I'm pretty sure I've seen studies that say, married or not, there's no such thing as a monogamous homosexual male. And promoting monogamy among homosexual females would have little effect on the transmission of STDs since they are far less likely than heterosexuals or homosexual males to transmit disease.

Also, promoting abstinence from premarital sex, if 100% successful, would stop the spread of STDs almost dead in its tracks. So why don't I see the same people who promote homosexual marriage promoting abstinence?

Well then I am sure you would support monogamous pedophiles as well....

You employ moral relative argument. There are absolute truths that one can not simply compromise away.
