There is nothing wrong with being lesbian gay bisexual or a transsexual. If we would all just accept everyone for who they are, and not force our opinions (such as religion) we would be so much happier. The classic example would be a family member such as a son/daughter who are kicked out for being LGBT. They are still the same loving person who you've loved your whole life, but just love a different gender than you thought they did. The LGBT community are full of extremely happy and kind people, and I don't see why you'd try to rain on their parade. This is coming from a straight man by the way.
The subject of this debate is very nonspecific, leaving me with the impression that a large part of this debate is to determine exactly what is being argued. Should LGBT have the right to marry? No. This is not because it is wrong to be homosexual, this is because marriage is a product of religion, thus it is the beliefs of the religion which should determine ones ability to wed. Since most common religions do not grant homosexuals the right to marry, it should not be given to them. It does not matter how happy or kind the LGBT community is, its beliefs do not mesh with the beliefs accepted by those who are religious. This is not to say that there should be no alternative, under the law any person should be able to unionize with any other in order to claim the tax and social benefits of shared living, however if they wish to get married they must conform to their chosen religions beliefs.

It is the LGBT community that is forcing their beliefs on to people. The churches do not want to marry homosexuals, so the homosexuals ask the government to force them to. That is an infringement of a priests natural rights, he gets to choose who to marry based on what ever opinions or facts he possesses.
