There should not, under any circumstances, be a re-definition of marriage. Traditional marriage has for centuries been tied to the belief that joins one man and one woman together to become as one, the basis of which is to procreate. A natural union. While in some instances procreation may not be possible that still does not negate the true meaning and intent. Arguments of those homosexuals who use the inability to procreate is not justification to accept their particular life choice being called 'marriage'. That does not make me a 'bigot', 'hateful' or 'homophobic' - choice adjectives used as bullying tactics to force acceptance.
To date, there is no known, scientific documentation that anyone is born a homosexual or, for that matter, that there is any recognized homosexual gene; however, I believe that many things in a young person's life may contribute to the eventual move toward homosexuality, albeit misguided. The American public is not being told the whole truth about this march to make homosexuality an 'acceptable, viable, alternative' lifestyle and the real truth of 'unintended consequences' is not a pretty picture.
