Your impression is flawed. Like most liberals, you judge a book by its cover rather than questioning what is written inside. First off, I don't give a fuck how people choose to live their lives; frankly I couldn't care less if two men or two women get married. Second, I left the Republican Party several months ago because they've abandoned the concept of individual liberty and small government (concepts which you, as a liberal, also reject). As for your other accusation, it is so childish it warrants no response. Grow up.
I understand that. However, if we are going to force gay marriage onto the states via the equal protection clause, then we must also permit close relatives to get married. What you view as being socially acceptable is completely irrelevant. So long as they're two consenting adults, the law must be applied equally.
On the other hand, who are we to limit a marriage to only two people?
That is beside the point. Even if there is one individual out there who wants to marry his sister, it becomes an equal protection issue (according to your interpretation of the equal protection clause, that is. Not mine).
You are the one who is creating a diversion. For instance, I didn't once include animals in my argument (it is an absurd argument to begin with); you chose to put these words into my mouth. If you're willing to discuss this issue like an adult, fine. Otherwise, do us a favor and hop on the next boat to fuckoff island.
