I was too young when he was alive, and didn't know anything about SC. Was CJ Rehnquist hated by the liberals just like Alito and Thomas nowadays, or more similar to Roberts?
I guess he might not be that hated. The nation was not as polarized, and he appears moderate comparing to Scalia and Thomas. But I would be surprised if he has a net positive review among Dems, as Roberts currently.
No he wasn't. He might've been a tad more fair and less hackish than Thomas and Alito, but he was definitely an archconservative through and through and quite hated.
For all the very understandable hatred of him that Scalia got, he was probably the most fair conservative justice the court has had in decades. A great example is his decision and casting of the effectively deciding vote in
Texas v. Johnson where he said that while he was utterly repulsed by flag desecration and that he deeply wished there was a way to prohibit in accordance with the First Amendment, that just wasn't the case.
