See, there are definatly going to be rather large psychological factors, and i can disagree to that. A male child brought up by a lesbian couple, for example. The child will probably grow up to be more femine than masculine, if the father figure is non-existant. But things change when put in social groups. The only REAL DIFFERENCE the child has, is the fact that he/she will have to learn the hard way how to act. The child will do 'social experments' until they get somthing right. When they do, they stick to it. Anyways, who said that the gay couple do not have parents, both fater and mother, who can be involved in the childs life? Children brought up by Homosexuals will have a tougher social life early on. Except from that, i dont really see anything that can excuse a homosexual couple from having children of their own.
