I have the expectation that a Supreme Court justice should be capable of the same degree of objectivity on a constitutional argument that I am capable of. I do not allow my own personal political views to influence my assessment of constitutionality. they should not do so either. It's one thing to have an underlying philosophy which guides their understanding of the constitution. I support all Justices having that and using it consistently. It's the lack of consistency that pisses me off. The blatant hypocrisy.
Scalia pisses me off the most because when it does suit his purposes, he makes the argument I would make. When it doesn't suit his purposes, he'll undermine the **** out of those same arguments.
