David Duke and his heretic Protestant brothers and sisters are an embarrasment to themselves and their heritage.
Western European culture, in my opinion, is the best to have existed in the history humankind and I say that as a non-European. Europeans have a right to take pride in this and to preserve their heritage, culture, and lineage just as any other people.
All of this being said however does not excuse any sort of supremacism, nationalism that supersedes Church teachings, racism, or any other such nonsense that is part of the staple diet of Protestant heretics or Orthodox schismatics.
