No one anyone has ever heard of.
That was pretty much Tucker Carlson's attitude, but his staff investigated MSNBC and Tiffany Cross after receiving complaints of her virulent anti-white racism from Tucker's viewers. Tucker showed clips of Cross to his huge audience. She reminded me of Malcolm X. Anti-white hate piled on anti-white hate. I suspect that some of Tucker's audience let their disapproval be known to Comcast.
