Homosexuals have a right to a civil marriage, as far as I know. Are you telling me, a homosexual has been denied a license to marry because they are homosexual? Where? When? I know of many homosexuals who did marry, so I know that some do indeed get married. Oh, I get it... what you meant to say is... "deny homosexuals the right to call homosexual relationships marriage, and be treated the same by society?"
Look...... IF the definition of 'home ownership' meant that you either owned or were purchasing a home, and the association of renters and leasers wished to argue their rights as 'homeowners' was being violated because they didn't get to claim their rental fees as a tax deduction.... you would say they were out of their minds, wouldn't you? The same is the case here. You want to call homosexual partnerships "marriage" and claim your rights are being denied... but you are not being denied anything. What you want to do is not "marriage."
