You don't see the sarcasm at all? It's a joke. Generally, gay people are considered to be liberal, and anti-gun. Not all, but some. Not all are married. Some, but not all. Some, but not all may have marijuana plants. Protect marijuana plants with guns? Probably not a great idea even if it were legal to use deadly force to protect property. I'm sorry you don't see it as the sarcastic joke it was meant to be. Unless yours was a joke, too.

Come on you guys, it's a joke. Generally, gay people are considered to be liberal, and anti-gun. Generally. Not all, but generally. It's a joke.
