Evolution has long been used by social darwinists and bigots to justify alienation and persecution of minorities.
Your understanding of evolution and the different facets of evolution is really narrow and... wrong. I am not saying that evolution does not take place. What I'm saying is that factors such as the survival of the fittest/evolution of a species takes place over millions of years. You cannot claim to be a fair judge of what is the "fittest". All you can do is claim that your individual type is the fittest and that is why you should be privileged. i.e. heterosexuals are surviving now, which indicates that we are the strongest, which means that everyone else is weaker. That is the anthropic principle speaking and circular logic. Which, of course, reflects more on your personality than evolution ever could.
Also, "mother" and "father" are extremely fluid (and homo sapiens-specific) terms. You may know that there are quite a few species of reptiles and fish that change sex several times over the course of their lifetime. Or you may not, and persist in thinking of the larger ecological world in terms that can only be applied from a human-centric (and therefore inaccurate) perspective.
You may be interested to know that many species of birds and mammals mate for life in a homosexual fashion. They continue to reproduce with opposite sexes, but biologists have observed that the offspring are raised by the committed homosexual partners. These species thrive and survive too, completely debunking your "theory". I suppose following your logic, because everything is genetic, straight people never have gay children, because it would go against the survival of the species.
I get really annoyed when people claim to be "individuals of science" and then follow it with a whole lot of ill-substantiated and ignorant nonsense about evolution and social darwinism.
Oh btw, I think after reading this thread that ENTJs are probably as misunderstood as any other type on earth. Some individuals make the stereotype.
