Homosexuals are worthless biologically speaking

I don't fully agree with this. If reproduction was still necessary in this age, homosexuals are still capable of reproducing. They have the capability, but what they lack is the desire. Is someone who is straight, but never wants to have children also worthless biologically? They both lack the desire. What you need is someone who lacks the capability. Those would be those born sterile or some other inability to reproduce naturally. But regardless, we don't have to worry about carrying on the human race as individuals anymore, :).
