I understand your thought process, but when you're faced with a choice of two evils, it's still a good idea to go with the lesser evil.
If I have to choose between Republicans who are giving away some of my freedom, or Democrats who will take it all, the choice, while it sticks in my throat, is obvious.
This week I'm sending a contribution to the NRA. I don't like all the internal politics that's going on, but again — in the lesser of two evils camp — I still think they're the best line of 2A defense around.
