I’m going to take another stab at this particular prong of your OP, since the other part seems to be covered pretty adequately.
I’ll start by stating up front that I don’t think you’re wrong that this is a common reaction among liberals. I’m just interested in your (in my opinion) badly misguided impression that it is particular prominent among liberals. Rather, it is my position that this is a common reaction of most non-lawyers, regardless of their political persuasion.
Let’s start with something suitably judicial. How about Judge Roy Moore? Judge Moore, despite being well aware of the supreme court’s interpretation of the first amendment, thought he should be allowed to display the 10 Commandments in front of his courthouse. When ordered to remove the monument, he refused. His actions won him widespread support among conservatives, who felt he should have been allowed to retain his monument, regardless of the court’s interpretation of the law.
Abortion is a constitutionally guaranteed right in this country. Abortion protesters frequently chain themselves to clinic doors, preventing patients from entering. While the protest itself can be seen as part of the political process of this country, isn’t physically preventing people from exercising their legal rights every bit an “end run” around the law as criticizing someone for enforcing it?
Going back to SOCAS issues, it’s pretty firmly establish case law at this point that it is illegal to teach creationism in publicly funded science classes. Despite this well-established law, conservative groups constantly push for it’s inclusion in school curriculums, going to some pretty extreme contortions to circumvent the first amendment.
The point, again, is not to argue that Republicans are worse. This isn’t a political trait. It’s just a people trait. Most people don’t really care *how *stuff works, they only care *if *it works. And that goes just as much for their government as it does for their television sets. When they perceive that their government is failing them (be it in allowing abortions or failing to protect gays) they don’t care why it’s broken, they just want to work the way they think it should work, and they don’t really care about how it’s done.
