Also I asked the same person this question I asked the immigration question you asked earlier in the thread. They said this.
I think that the first part of the statement is correct. Conservatives care more about the courts than the left does most of the time. But its kind of minsunderstanding the conservative view of the law. It isn't original intent that is supposed to be the controlling factor. Its original meaning, what the people who ratified the constitution or amendment in question thought they were authorizing. We do know that the idea that originalism is just a rationalization for conervative tendencies is wrong because of cases like Texas V Johnson, where Scalia ruled that Flag-burning is protected speech despite his own wishes. But there are actually now lots of left-wing originalists. So its kind of a moot point. I don't know that Ruth Bader Ginsburg is a left-wing originalist. But some of her public statements about the civil war amendments and her dissent in Macdonald V Chicago kind of hint at it.
I guess more to the point, the fact that there are now left-wing originalist think-tanks proves that originalism isn't just a rationalization for conservative tendencies.
