Again, from the top: The Left is the enemy of God, Man, Freedom and Democracy. It hates and seeks to destroy the heritage and values of the Christian Faith, the Christian West and the American Experiment. To that end, anything willing to join the Left and seek the demise of its enemies is its friend.
Likewise, any who oppose the goal - including Muslims, blacks, American Indians, women, Jews - become the enemy just the same. No amount of ethnic slurs, racist attacks, anti-Semitic dog whistles, sexist or misogynistic attacks is too much for them.
