What holds all those folks on the conservative side together, fundamentally (along with a few substantive issue) is hatred of liberals. Disgust, on a very deep, gut level, and a sense that conservatives are marginalized in the institutions liberals control and a sense that they manipulate language and procedure to control those institutions and to keep conservatives out.
Whether they are libertarians or Christian conservatives, they usually have some combination of anecdotes that reinforce this perception, and they’re not always wrong. The sense that liberals control “everything” is obviously stupid � but it’s a sense of local injustice and mariginalization that usually motivates people, and in the mainstream media and universities, there’s probably something to it.
So I think looking for the glue on the positive side of overlapping ideology is probably the wrong way to look at it � the negative side of shared resentment is the better way to go about it.

Yes, they hate liberals for their freedoms – to think, to be able to hold more than one opinion at a time, to value diversity and the free range of culture, etc, etc…
I really think most conservatives are jjust flat-out threatened by anything they perceive of as different, for fear it could actually be something interesting and of value. The fear that drives these people amazes me.
