That's literally a pile of bullshit. Imperialism wasn't what introduced blacks in America, it was slavery (I don't think the the few Jews involved single handedly manage to relocat millions of people by themselves). But you know what will bring for sure blacks in your country? Conquering them. Then you are literally asking to be in the same state as the blacks. Imperialism and ethnonationalism are totally opposite. You may be pro white, but on a broader scope, you are going in a route totally opposed to mine.
