Weird how people are saying it should work, lol. Blocking YouTube ads with pihole most definitely does not work. Cannot work even, it’s just how YouTube works.
I’m afraid that using something like a googletv stick (or nvidia shield etc) and installing smarttube is your best bet.
American culture is interwoven with the black slavery history, most of the rest of the world is not. So no, they don’t have that baggage when it comes to black face or the like. Like you don’t understand the Indian caste system, for example.
Making them out as racists is stupid if you stop to think about it and not just give kneejerk reactions. Not everyone is as obsessed with race like Americans.
