But Maizie why label them at all?
Because that's what happens and no amount of virtue signalling is going to change it.
Now we're back to trisher's opening contention, aren't we? If labels are used why is it acceptable for people to be labelled as communists, trots, marxists, lefties, loony lefties etc. (even if the label is not justified) but not fascists?
Though I have to say, as a veteran of 4+ years of 'discussions' on the politics threads I have rarely, if ever, noticed another poster being called 'fascist'. Whereas the list of names I've cited for those from slightly to the left of centre to fairly far left of centre recurs frequently. I think we just tend to ignore it as being born of ignorance We just don't go running screaming to the mods about it.
I do think it perfectly valid to refer to a government as fascist if it ticks the boxes. Indignant squeals about Nazi Germany and the Holocaust are, IMO, a refusal to face up to reality.
