Its not that others don't borrow etc. To me, its that the far right just straight up steal everything because its not an ideology of idealism, despite the words they use. Its just an ideology of power and they use any method they can to get it. It doesn't really stand for anything like, say, worker emancipation or the unity of human, spirit and nature which are the things you would draw from when making your own cultural identities.

You can't really advertise, with a symbol, your policy being the will to dominate and expect positive results.

In fact, the far right ripped off everything associated with them. They very deliberately don't set trends but follow them, as this best facilitates their aims. For example, original skinhead culture had nothing to do with the far right and was only meant as a way for working class to distinguish themselves from the hippies, who they saw as upper middle class.

Of course, everyone knows the "steal from one person is plagiarism but steal from many is research" line. My point here is that almost all of the others, to me, would fall under the "research" umbrella whereas the far right would all be under the latter. At least, thats how I see the difference.
