I will make a secular argument against homosexuality but before I do, if anyone has logical reasons to think I am wrong then bring them on, but if as in most cases your objection is simply your emotional preference dressed up in a mere veneer of logic then please do not respond to me.
1. Homosexual acts produce far more damage than any potential gains can justify. For example 4% of the US population are homosexual yet they create 60% of new aids cases, and homosexual life spans are drastically shorter than heterosexual life spans. That is just the tip of the ice burg.
2. Heterosexual acts do cause some damage but far less than homosexual acts do and unlike homosexual sex heterosexual acts are necessary to perpetuate the human race.
That is my preliminary argument. Again don't bring emotion to a logical debate, these discussions are always disappointing and at this point I will no longer waste evidence on an emotional position.
I was also asked to post some evidence and I gave a few examples in post# 268 I believe. I will not spend time going through past posts after this point.
I'm glad someone's done this, a nice development. OK:
1) The association of the spread of HIV with the homosexual population is of course associated with men, not women, for starters. And it is preventable - the propensity to partake in risky behaviour and to suffer depression are features of what is called minority stress. The more we accept people whose attractions are towards the same sex, the less these problems will exist.
2) No they're not, we have modern technology.
