Please explain what you believe White Nationalism is.

White Nationalism (in the US) is a political movement that asserts that the US should be a nation run by and for Caucasians.

There are people of other ethnicities that are part of the White Nationalist movement.

I've never heard of that organization. Do they have a web site?

I wasn't talking about an organization, I was talking about a movement. There are numerous different organizations of various sizes, as well as individuals, who are part of the movement.

None of this is new -- white nationalism has a long and well-documented history. As with all political movements, the exact moment it started is a little fuzzy. Some place it as far back as 1916 with the KKK, but I think that most people place the modern form of it as starting in 1974 with the National Alliance.

What point are you trying to get at? There are plenty of ideologies and political ideas that aren't represented by a singular organization advocating for them.

There isn't a point he is trying to get at, because he isn't arguing in good faith.

I'm having a hard time understanding if you were downvoted for correctly pointing out that "nationalism" and "white nationalism" are two very different things, or because you described both as objectionable.

I wondered the same thing. I suspect it's that I said I considered plain old nationalism objectionable. That term can have very different connotations to different people.
