Yup.
Words like "racist", "sexist", "bigot", "whatever-a-phobe" no longer really mean what their dictionary definitions say.
Words evolve to take on alternate meanings based on how they're most often used at the time.
awful - Once referred to something that was full of awe, as in a good thing. Now it means something that's bad.
meat - Once referred to any food product. Now it means the flesh of animals.
bachelor - Once referred to a low ranking knight in medieval days. Now it means an unmarried man.
Racist, sexist, bigot, whatever-a-phobe - Once referred to persons who hated others based on their characteristics. Now it simply means "one who has disagreed with the radical Left".
