You may want to look at the history of these channels before posting their content. If this guy doesn't walk around wearing a shirt that says "Neo-Nazi FTW", I don't know how it could be more clear.
So I just had a look and it was all left wing topics? Very critical of US imperialism and Zionism/nationalism. Generally not topics you see rightists ever talk about.
It’s got huge tankie vibes I’ll give ya that, but nothing at all neo-Nazi?
Zero Nazi content. Only a bunch of amazingly well sourced videos often about American foreign policy. Mostly quoting important figures like American presidents, foreign policy heads or CIA employees.
If you look into a channels history before watching a video you're not learning much.
