Incest, homosexuality

[TheDarkestOfAngels]

I'm interested to know what people have to say about why homosexuality should be allowed/accepted in society, and incest should not. This is under the assumption that the incestuous couple will NOT procreate if they get legally married, and of course are consenting adults.

I don't approve of incest when
1) It has any chance of being due to or resulting in psychological trauma, more than non-incestuous relationships
1A) Gay relationships start and end with all the stops, whistles, and breaks that all other relationships have and there is no evidence to my knowledge that a gay relationship is any more damaging psychologically than heterosexual relationships (very different from incestuous relationships)
2) No gay relationships damage other people. Incestuous relationships (to a point) have a far higher chance than average of resulting in genetically disfigured children that can result in permanent and serious complications.
2A) Gay relationship never result in children, except through adoption. There is no evidence that gay relationships damage children at a higher average than heterosexual relationships (very different from incestuous relationships) when children are involved.
3) Incestuous relationships are far more damaging to familial ties to all involved family members. By the very nature of such a relationship and depending of the kind of relationship, it even has the potential to destroy an entire family.
3A) Gay relationships don't always have any affect on familial relationships and are irrelevant to the immediate family at best and destructive to the gay individual's relationship to his family at worst and rarely threatens an entire family unit (think of a married father porking his own daughter and the effec that has on - the father's wife and other children). At worst, a parent-turned gay becomes estranged to the rest of the family and turns the other parent into a single parent.

This is, of course, excepting major taboos and even ignoring the fact that incest is far more taboo than homosexuality and largely for the above reasons. Certain kinds of incest are illegal for those reasons and other kinds of incest where all three (or at least the first two) are not the case are actually legal - such as between two first cousins in many US states.

Homosexual relationships have not been proven to be any better or worse, overall, than heterosexual relationships and can be just as healthy or destructive.
