Can use myself as an example that this is bullshit?
Before I was targeted for violent abuse my political beliefs were somewhere between being disillusioned Labour and Green party. After that I started moving further towards the libertarian left and now my beliefs are borderline anarcho-syndicalist/anarcho-communist (although I like anarchism without adjectives in it’s original sense as an idea.)
It is true that I don’t think of myself as a liberal anymore, but I am definitely not a conservative/reactionary. I’m happier with radical left, or just radical.
