i agree with gay marriage because it is not fair to them that only man and women who are in love can only get married.
Valid

I have found that the majority of people who claim others use fallacies haven't the faintess clue about how they work.
Invalid

Marriage was never defined as between a Man and Woman until religious Zealots pushed the Government to define it in such a way to deny Gay people their right to marry.
