What do you think that separates a liberal and a SJW?
They're both supposed to be on the same left side, but one takes it far far away to the extreme while the other is considered more of a decent open minded human being.
SJW are more aggressively liberal. Everyone is liberal to a degree. I guess I could "spot" a SJW if they had colored hair like turquoise or purple and had thick rimmed glasses.
