It's also to do with the language, and it's appropriation.
With most of the MSM , "right" is kept to deserve something bad, beyond the pale or undesirable. It was not always this way of course. Mussolini, creator of Fascisn would be undoubtedly thought of as " right wing" now, despite the fact that he was a revolutionary socialist, twice deported from Switzerland for activities in that name, long time editor of Ill Populo, which though little recognised now regularly lionised the Communist movement. So much so actually that Lenin praised Mussolini in Pravda before his death, calling him " the future of our movement".
It's all in the language. Stalin knew what he was doing when he excoriated fellow communist Trotsky as " right wing", before having him bumped off.
But a nutter is a nutter is a nutter, no matter what strip he wears.
