Some right wing nutjob went to the SLC protests with a machete and fired a bow at the protesters. There are absolutely white supremacists showing up to instigate.
The far right's goal is to create an ethnostate through any means, including genocide. Even if anarchists' main goal was to create chaos(it isn't), they're not even remotely close. Circular political theory is one of those things that sound good if you don't understand these movements but have no basis in reality. Further, antifa is not an organization, it's an ideology. There aren't really any clear organization you can point to as antifa, whereas with White Supremacy you have the Proud Boys, KKK, Aryan Nation, Stormfront, three percenters, etc.
