I still don't get that thinking. Just because homosexuality is "incorrect" in terms of reproducing, that doesn't make it "incorrect" as a whole. Yeah, if your goal is to pass on your genetics along with the genetics of another partner, homosexuality is a stupid choice obviously. However, with adoption and other methods of obtaining a child, I don't see how it can still be viewed as "incorrect". If the goal is to raise a happy healthy child in a good home, then homosexuals are capable of doing so just as well as heterosexuals, and are actually better in doing so in many situations.
Read carefully so that you will understand nature better:
Naturally for living organisms the goal of the alpha male is to pass his own genes into the next generation. That is goal numero uno.
Naturally the alpha male will impregnate many females. Afterwards the female will seek beta males to take care of the offspring.
Gays with adopted children are only playing the part of being the cuckold for the alpha male that passed on his genes. They have been intercepted by the alpha cuckoo bird while betashly thinking otherwise.
They blissfully go through life without realizing their mistake, and their bloodline ceases to exist. Their family goes extinct.
