I can see two problems with a son marrying his mother that are not related to Christian morality. The first is the issue of '
grooming' which then means the son, in the eyes of the law, becomes a victim. The second issue is the potential product of such a relationship. Children borne of incestuous relationships, this gives you another potential victim. Homosexual relationships don't produce mentally and physically handicapped children, last I checked they don't directly produce any children.
That is why I disagree with your statement. I think you intended it to be an emotionally charged statement to induce a sense of revulsion in the general reader. I think that it is disingenuous in that respect.

"Debate is an art form. It is about the winning of arguments. It is not about the discovery of truth. There are certain rules and procedures to debate that really have nothing to do with establishing fact ” which creationists have mastered. Some of those rules are: never say anything positive about your own position because it can be attacked, but chip away at what appear to be the weaknesses in your opponent's position. They are good at that. I don't think I could beat the creationists at debate. I can tie them. But in courtrooms they are terrible, because in courtrooms you cannot give speeches. In a courtroom you have to answer direct questions about the positive status of your belief. We destroyed them in Arkansas. On the second day of the two-week trial we had our victory party!"
