I haven’t been following this massive side-thread, but maybe you are getting downvoted because you are using white supremacy to describe anything that structurally favors white people. Policies that merely favor white people are not necessarily “white supremacist”, unless those policies are also motivated by a belief that white people are better than other people. Maybe “structurally racist” might be a better way to describe the things you are describing? But what do I know, I’m not a sociologist.
