Travis McGee, you are CORRECT! Just think, if this crap was genetic - it would have died out thousands of years ago - you can't pass genes if you don't reproduce those genes!
This is a deviant, perverted learned sexual behavior! Period!
Do a survey on how many women like circumcised versus uncircumcised - Uncircumcised is all natural, yet most women will opt for the cultural norm - taught sexual preference!
Another example of learned behavior vs. "I was born this way" - Most men are hard-wired to lust after women, but parade their naked sister in front of them....Yuck! A taught thing!
It's all a matter of what the rules are and who makes them up
Think about it. We do have rules on sex for many reasons - health, keep people from killing each other, etc.
The majority of us "Normal" people need to stop letting the minority of perverts make the rules! and keep the rules that have worked. I am no homophobe, I just call evil what it is - EVIL!
