I agree! But in the case of 'alt-right', I don't think the word was hijacked by White Nationalists. They are the ones credited with coming up with it and they are the ones I can first recall using it.

I moved this up a couple levels since we keep hitting the nesting limit.

I don't disagree with that.

Yet also a thing that can be important is where a person first learns the meaning of a word/label.

It appears that a huge amount of people that self identify as Alt-Right don't even know those White Nationals are there.
