If you go around calling yourself a "White" nationalist to those who have been trained to be anti-White and find such a mindset as "anti-Semitic" and just unacceptable, you can expect to be alienated. In other words, if you want to help the cause, do not confuse people to what you actually are. There nothing wrong with opposing the genocide of "White" people. There nothing wrong with what you stand for! So don't give any other impression.
Having said that, if you are "White" and agree "White" people should have rights like non-Whites have, to have their own territories, their own organisations and industries, etc etc, then, whether you realise it or not, you are a "White" nationalists! It's really not a dirty word or a shameful mindset.
I'd say being willing to surrender your loved ones on the alter of political correctness is shameful. I'd say being willing to take food out of the mouths of our own in need to feed foreign people that can't feed themselves is shameful.
Most "Whites" who are in fact "White" nationalists, are not motivated at all by supremacy! Bit different to, for example, a Chinese nationalist, living in Australia, who has his own country, but call us "racists" to silence us. Like we are a pet dog that fears it's master. . We don't have a "White" supremacy problem! We have a "yellow ", brown and black supremacy problem!
