Good for that guy, hate is a cheap but addictive drug. I don't really see the problem with his new beliefs. The major problem for a lot of younger white people is that they've been raised with a lot of undeserved guilt about their race and their heritage, which then in many cases leads to an extremist response once they begin to dig a little deeper. Not unlike the red pill with women.
It's perfectly ok to have part of your identity be 'white' and want your historically white nation, to remain white and have a desire for your children and grandchildren to look like you. You can also arrive at the moderate position, that areas and nations have a dominant ethnicity and culture, but with room for other ethnicities and culture. I consider that the normal and healthy way to view yourself in relation to the world.
