There is nothing wrong with the words "Judaizer" or "Pharisee." A "Judiazer" refers to a non-Jew who adopts all or part of Jewish law voluntarily, while not fully accepting Judaism. It's a perfectly fine term. In fact, I can't really think of any better term to describe Christian sects that do things like keep the Sabbath or the laws of Kashrut.
Modern Rabbinic Jews are all Pharisees. Heck, we're proud of it.

I agree with both propositions. The point is the people who usually throw those terms around (including here on FR) intend them as insults.
