I think if my child was gay I would be devastated. I can say I would not want to be a part of that part of his/her life. I don’t think I would disown him or her, but the partner or their “family” would not be welcome.
If I knew my child would be gay would I alter him or her? It depends on the risks involved. It may be all PC on Slate to say you want gay kids but to prefer it? Yea, right. Gay kids means end of the line genetically speaking, especially for gay men. No grandkids. No greatgrandkids. Sure there is adoption, but it is not the same. It is a fact of evolution, propagation of the species. That is one thing gays can’t do.
