My take on it as well. I think he explained it as clear as it can be explained. I am White. I love the Nation of America. Hence I am a White Nationalist. To be shunned by Oath Keepers. O.K. by me.
You’re not being shunned by Oath Keepers.
Is there a better group?
I'm there also. I am a white male who grew up in a dysfunctional home and worked his way up through the opportunities provided by our NATION. I never thought I'd see the term "nationalism" connected to any race or ethnicity.
na·tion·al·ism /ˈnaSH(ə)nəˌlizəm/ noun: nationalism; plural noun: nationalisms
identification with one's own nation and support for its interests, especially to the exclusion or detriment of the interests of other nations.
synonyms: patriotism, patriotic sentiment, allegiance/loyalty to one's country, loyalism, nationality;
More: advocacy of or support for the political independence of a particular nation or people.
As the dictionary defines nationalism, it has NOTHING to do with race, ethnicity, gender, age or other. We need our side to call those racists every time they use that term. However, white supremacists is another matter, but they come in all colors.
