No, they should not intentionally bring a child into the world without a father. No, it is unthinkable for a father to move away from his children. An alien parachuting in from Mars and seeing the vehemence of the campaign against Dr. Laura would naturally assume that she must have said some really awful things about gay people.

All creatures have a drive to reproduce.
That is the usual course of nature. If the sex drive is diverted from its natural object onto something else, precluding the possibility of procreation, that suggests an error. To a Darwinian even more than to a Bible believer, homosexuality must seem to be maladaptive. To hear the Gay and Lesbian Alliance Against Defamation tell it, terms like biological error are just the fuel gay-haters need to go on violent rampages, maiming and killing homosexuals. This is patent nonsense.
