I love watching people trying to justify forcing religious beliefs on others and then turning around and saying its not because of their religion....
Get my point? Overwhelmingly, the people who are against homosexuality are also Christian, or religious in some sense. They have already come to the conclusion that homosexuality is a sin, and it's wrong, and it's evil, and it's a choice, because an old book says so.
Based on this presumption, they then search for reasoning to back up their position. Of course, to properly come to a conclusion, they would have to have none to begin with....
