Is it OK to have a opinion about someone's private/sex life? No, as long as no one is at risk from harm. If you want to have such an opinion, keep it to yourself. Using it as a reason to try and justify withholding a right to a person is wrong.
Is it OK to have an opinion on on war, smacking etc? Yes, because where peoples rights are being violated, as a good human being you should try and stand up for them.
Why are you bringing sex into this discussion?
Because that's what this entire argument is about at its root. Also you brought it up 2 pages ago.
No I never. Quote me
The root of this argument is "gay parenting", thats got nothing to do with sex.
Its similar to you implying that sex between me and my wife is the root of how I bring up my kids.
Quote for you then:
Klipspringer: I disagree with people who "swing" in their marriages. I disagree with the "swinging lifestyle" just as much as I disagree with the "gay lifestyle.
