I don't have any problem with Liberals from a political standpoint. I lean to the Conservative side but I have several liberal beliefs on issues like abortion, drugs, gay marriage etc. This is why I have voted for Liberals in the past, both in federal and local elections.
But when it comes to Liberals as judges, I have no use or tolerance for them. A Liberal judge is usually someone who tries to legislate from the bench, and I want no part of that. If you want to institute social justice on a particular issue do it the right way and pass a Law in the Congress.
There doesn't need to be a Liberal or Conservative test when it comes to the Judicial. The test should be on how diligently they have adhered to their prescribed role in the process, which is merely to interpret the Laws that are passed elsewhere. End of rant.
