There is no "fact-based" discussion that starts with the assertion "SJWs deny all truths." It's not just technically false, it is nothing more than your unoriginal ideological biases showing. It also makes me wonder how much real-world experience you have.
From long experience, attempting to engage with people like you is a tedious exercise in batting down one bad faith argument after another.
I'm not going to engage further, but for the record, it is a statement of fact that the overwhelming majority of the overt white nationalists of the world, especially in America, are on the side of "anti-SJWers." Another way I put it: not all conservatives are white nationalists, but all white nationalists are not liberals in 2020 America. That Venn diagram really should give you pause if you're not a white racist, but it doesn't. Hence, the tediousness of this exercise.
Peace out.
