While true, the left/right axis becomes meaningless if we allow each side to define themselves by only their well-behaved adherents. For example, it would sure be convenient for Republicans in America to claims that Trump isn't really on the right, and he doesn't represent their views. In this case, the values embraced by Marx overlap heavily with values often held by people who describe themselves as leftists.
That said, I actually do think the left/right axis is meaningless. Humans are so much more complex than a reductive spectrum.
Was it? Seriously question. That wasn't made clear to me when I signed up. I never would have signed up had I read that. I suspect the intensity of your views and those of the owner of this instance differ somewhat.
