they think their way is right and ought to be forced on others via the law, while the liberal says live and let live. It is so twisted but what the call "intolerance" of them is merely disagreement with them.

They are the ones who want to exclude other people who think differently. They don't want to do business with gay people, won't bake the cake for the wedding. The liberal could be a devout Buddhist but still is willing to do business with and bake cakes for people who are of other religions and gay people, etc. They do not exclude people who do something different.

Authoritarians simply can't get their minds around the concept of "Live and Let Live". Everyone has to think, feel and do as they do or it somehow threatens their narrow world view. I just see it as extreme fear and insecurity.

and the Fundie preachers in their churches.

They are unwilling to separate the two.

This is really what is at the core of so much of the hostility the right has for the left (and anyone else who doesn't think and feel EXACTLY the way they do.) They simply cannot tolerate that another viewpoint even exists, let alone that people are free to live as they choose. It's coming from a place of deep insecurity, I think.
