White themselves don't know what White culture is because schools and universities prohibit the teaching of the superlative cultural achievements of Western civilization.
I was the only university professor in Canada, and possibly the entire West, who focused on the unparalleled achievements of Western peoples --- which instigated an academic mobbing against me (by university professors) in 2019, forcing me to take early retirement.
I post a lot about Whites achievements precisely because diversity and integration with blacks (contrary to the childlike expectations of conservatives) inevitably entails the complete erasure, revision, or reinterpretation of 97% of human accomplishments in the Arts, Sciences, Exploration, Philosophy, Literature, Architecture, Music.
White culture = around 97% of human greatness. But schools and universities are now dedicated to "critical thinking" = overcoming "White supremacy" and "ethnocentrism" to "create a truly inclusive culture" where nonwhites and immigrants feel "welcomed" and "validated".
So, schools and universities teach lies about how White colonialism kept other cultures behind, how the West "stole" the achievements of nonwhites, how the West has always been multiracial or how we are all "connected" and how Africans, Muslims, and Haitians played "critical roles" in the making of Ancient Greece, Rome, modern science, and the Enlightenment.
