That can be kind of a good thing, though, right? Gay marriage and evolution are already arguments that are falling off the conservative map at a rapid place. In another 20 years, will "conservatives" effectively be just liberals who don't like socialism? That seems to be the way that politics have been boiling down to: socialism vs capitalism. Everything else is kind of adjacent, but as laws get passed or ideas get effectively mocked on the internet, they drop off because they aren't core to those two fundamental ideas.
