This is a very interesting topic to me. I sometimes like to think about things minus morality (my mom thinks i'm psycho when I talk like this)
But When I consider the homosexuality movement minus right and wrong, it opens up a lot of questions for me.
From a purely biological point of view. Homosexuality disrupts the natural life cycle of an organism. An organism should be born, mature, reproduce and then die. Homosexuality cuts that off at the "reproduction" point.
People like to claim that 25% of doplhins are homosexual, but considering the very high infant mortality rate amongst dolphins homosexuality would wipe out the species.
Economically speaking, the gay lifestyle is costing millions in healthcare. Even thoguh Gays are the minority, they represent a diproportionate number of new HIV cases.
On the other hand more homsexuals means less children. Less children/people means less strain on the economy across the board, but I imagine planned parenthood is taking care of that without any negative side effects like health care costs.
I could go on and on with speculations and quetions.
Looking back at history I've learned not to blindly trust what "scientists" say. Scientists will say what ever they have to to get grant money.
I could go on but I've gotta log off now.
This is a very interesting topic. I hope we get a good discussion going.
