It’s very clear that a large number of Assad supporters have no idea what fetid political forces they have aligned with, that in fact they are marching with fascists & white supremacists. If they knew, they would be horrified because that isn’t how they see themselves.
But in human life there is the subjective & the objective: what one believes about reality & what is. When you equivocate or support Syrian & Russian bombing of civilians or US bombing of civilians, you objectively stand on the side of autocracy & fascism even if in your mind you believe you stand for peace & justice. In the end, if you facilitate the victory of fascism in Syria, who in the hell cares what is in your head?
