an openly racist president
Trump supporters would argue he is not a racist (and they have a large inventory of items to refute the notion) and that they themselves are not racists. I suspect one reason they may actually feel they are not racist stems from Republican political leaders who have for years denied any racism in the party and possibly the Republican base has been indoctrinated successfully into believing they are not racists.

In regard to Pres Obama, many of them would say racism did not exist until Obama was elected.

So what is the virtue of being a white supremacist?

ignorance is the enemy
without equality there is no liberty
