Gay Rights = Human Rights.
An Argument.
Gay Rights are Human Rights. If you do not believe in Gay Rights, you do not believe in Human Rights. Gay Rights mean marriage rights.
For Human Rights, I do not believe there can be an opposite opinion. For Human Rights, I will look into your face and tell you that you are wrong. For Human Rights, there are no qualifiers. That's some pretty radical statement, I know. I know that according to the rules of rhetoric, it is erroneous to say: there can be [no] opposite opinion. Human Rights are worth such extremism.
