I'm a Libertarian not a Democrat so I wouldn't even be laughing at myself. I even somewhat agree with a couple of the points. I just think the quip about marrying animals was a tired joke 10 years ago, not to mention it wasn't even a joke for some opponents of gay marriage but an actual serious argument they'd consistently put forth, so to see it lead off with that kind of sets the tone in a bad way. A lot of these have too much of a political edge to be humorous. It's more like constructing strawmen to knock down.
Sorry, I probably shouldn't have said anything.
