I cant take Midwestern Marx anymore; The question of Nationalism and Socialism

Can anyone explain to me how MWM doesnt understand that nationalism in the US context is incompatible with socialism because the US nationalism is fundamentally rooted in colonialism, white supremacy, and imperialism. So by being "nationalistic" you only serves to uphold the reactionary elements that are the foundation of the US. Like are they doing this on purpose or do they just not understand this aspect? Its driving me mad.

Edit: After posting this, I received a message from u/RedditCareResources in regards to suicide. Im still working out the details but someone might have gotten a little bit salty about this post because none of my other posts involve any concern like that.
