You are being obtuse. I have already stated my point.
All of the pro abortion people who proudly proclaim a woman has a right to do with her body as she sees fit reached their moral limit when it comes to incest.
The pro-gay people reached their moral limit.
When it comes to your body your choice, yes, there is a limit to what society will allow.
You're conflating issues that are unrelated, which seems to be a common problem with you, but even worse, you're completely misrepresenting the arguments of your so called "liberal pro-abortion pro-gay people." It is possible to believe that something should be legal while simultaneously having no desire to personally engage in the behavior. Let me break it down for you:
I believe gay marriage should be legal despite having no interest in having sex with men or wanting to marry someone of my gender.
I believe abortion should be legal despite having personal reservations about someone I'm sexually involved with (which would just be my wife at this point) potentially seeking one (I would support her choice, but I would certainly offer my own opinions on the matter which are more complex than we need to get into here).
I believe grown adults should be legally allowed to have sex with their relatives despite having no personal interest in fucking my brother.
I believe drugs should be legalized despite having no interest in getting high.
I believe that we shouldn't attempt to legislate morality, and that as long as an individual's behavior or actions aren't legitimately harming a non-consenting party, we should leave them be with whatever fucked up shit they want to do no matter how distasteful I might personally find it.
