Right - it is bad enough when a man and woman marry, create a child together, and then divorce.
But imagine the lesbian and gay male couples who hire surrogates or sperm donors, bring into being a child through unnatural means, and then decide they really should not have done the whole thing in the first place?
There are going to be some strange, alienated kids growing up as a result of the selfishness of adults who just HAD to prove their point.
