Yes, call him out on it:

These liberal/progressives deserve to be called out–every single time–on their hypocrisy. Don’t hold back calling them the “r” word, because they surely would not, if the tables were turned.

Yes (though they’re neither liberal or “progressive” — their ideas are some of the oldest ones in the book). I long ago lost any compunction in calling them racist, because they have no problem whatsoever falsely accusing me of that. And in their case, calling them out on it has the additional virtue of actually being true.
