The problem with sexuality has nothing to do with football. Nothing to do with marriage. But everything to do with the fact that sexuality is like a pendulum. Very few people on this planet are 100% straight and 100% gay.
Most of you will deny it but at some point - you may have had curiosities - tendencies - man crushes - you may have used alcohol as an excuse why you may have accidentally "played" with your buddy that one time in college or grade school...
You would not believe how many people in this society go both ways - but identify as straight and gay. The numbers are so high - that is the reason why it creates such tension and instability in politics, religion and society.
Do you know how many married str8 men play with other men and straight married women play with other women (which in society, is ok, as long as they are drop dead gorgeous, right)? Check out your local craigslist or adult friend finder sites - the numbers are there. Sexuality will never go away - as long as the straight society continues to act like its a choice when the funny thing - you never wake up one day and decide to be str8 or had any question about it? It's not a switch.
We have done experiments on OKCupid - Match.com and Christianmingles websites - we created straight and bi test profiles on these sites - and then took the opportunity to hit on other straight guys. The numbers are alarming as the number of men who have responded favorably to our solicitations. Not all men - but a day wouldn't go by where at least 5-8 straight guys would either hit up our profiles or respond favorably to ours.
Common responses:
"Although I am straight, I do have bi curious tendencies..."
"I'd be willing to play with another man as long as a woman is present in bed..."
"I am definitely bi but can never actually go through with it..."
"Catch me when I'm drunk and I'll play with you in a heartbeat..."
That folks - is the reason why this topic - which is nothing more than being freaking HUMAN - is nothing more than a joke because humanity is so insecure with itself.
If you have create a law that hurts a limited number of people just to prove your morals or faith, you have no true morals or faith to prove.
