In your original comment, swap 'white' for any other race. Swap 'men' for 'women'. Now appraise whether the comment is racist with those new terms in. Geddit? See how that works? There are only two logical options. You are racist and sexist, or you believe that you can't be racist to white people, and you can't be sexist towards men. If my elementary grasp of simple logic has missed a third possibility, please let me know.
