FWIW I beleive there is a genetic component to being gay, there have always been gays since biblical days, it's always been at around 5% and I have no problem with acceptance of people being who they are, I wasn't sure why so many actors ended up being gay but it made sense once I realized they had already been acting thier entire lives in order to "act" straight in a society with very little acceptance of it and so they might as well get paid for it.
I dont have a problem with gay marraige, Ive seen lots of stories of families denying visitation to loved ones in the hospital dying or otherwise because the family of the person in the hospital didnt approve of the relationship. Two people who genuinly love each other should have all the benefits marraige offers.
My problem comes with gay adoption. A kid growing up can't help but be influenced by the enviroment they are raised in, it is a skewered view of normalcy that has an influence whether the alpha-bits want to accept it or not. I stand by my statement that we will find out what the results of this social experiment will be, maybe they will grow up to be the next leaders of industry and etc., but my guess is they will be inmates after they off thier "parents" or go off on society for allowing it to happen in some mass shooting way.
