Yeah, the child might be missing out on the influence of a biological mother's presence in the household, but ultimately, children just need unconditional love, support, and discipline from their parents -- whether or not it comes from a straight or gay couple. Biologically speaking, humans have evolved for sexual intercourse to be the means of fertilizing an egg with sperm. However, I believe everyone has a right to bear/raise children regardless of sexual orientation. We have the means and the technology to do this, and no one should be told they shouldn't be allowed to have children. However, you do bring up a valid point about the benefits of a heterosexual couple raising their own children. Like I said though, all children need is a little bit of love and some guidance on the side.
