Let's repeat my statement for those who still have issues with context.....Any "movement" that supports 1 race over another, and/or claims a superiority of their race over others, is by definition a racist movement......period
In other words, they're not required to claim they're superior to anyone else to be a racist organization. Of course they should proud of their culture. Once you enter the United States however, you are an American 1st, culture 2nd. That doesn't require you to absolve yourself of your culture, merely that its part of who you are, is all.
And if who you are is also racist, you're going to be called out on that
