Trump's base are conservatives, mostly Christians, who do not consider themselves (ourselves) to be racists or supremacists and don't like being called that.
On the Proud Boys, if I remember correctly, Trump's words were to "stand back and stand by" -- it was the "stand by" which got Trump in hot water, because it suggests he might want them to stand up for him later.
As for condemning Proud Boys, Trump said he didn't know much about them, almost nothing, but he condemns white supremacists, assuming they are.
Are they?
Well, if one just dared to do a little research (this includes Trump and his staff), they’d notice things like ethnic diversity in online photos.
The International Chairman of the Group is Enrique Tarrio of Afro-Cuban ethnicity. Given his ethnic background, I’d say it would be pretty tough to rise to the position of Chairman if the group were of a White Supremist philosophy.
They're not "racist"....they're races.
