How about instead we say, "appointed by a Republican president," so we don't get bogged down in semantics? Since Heller, Citizens United, Bush v Gore etc were clearly the products of partisan Republican justices.
Sorry to be blunt but this just goes to show how often your "feelings" diverge from objective reality.
One can be moderately conservative and still conservative. If you look at the court's decisions, the only time in the last one hundred years SCOTUS has had a sustained liberal streak was in the 1960s.
Maybe your definition of conservative is not the same as most conservatives, but that’s just how it is.
