I wonder if it's in part because it become too easy to call people right wing/racist nowadays.
Things like vote Brexit = racist gammon.
Express concern over uncontrolled immigration = racist.
People lash out if they don't feel listened to don't they?
And agitators will exploit that. And scum/opportunist arseholes will jump on.
I have been interested in politics since I was a teenager, and have read widely on all sorts of ideologies.
Personally, as a retired civil servant having served ministers and had dealings with officials from all the main parties in the Republic of Ireland, I have no preference for any. Possibly too cynical of them all, but I always vote.
On your point about labelling, I have a well-thumbed 1979 Penguin edition of 'Fascism - a reader's guide' edited by Walter Lacquer. It contains 12 excellent essays from various academics, but one in particular, by Zeev Sternhell, who was a Senior Lecturer at the Hebrew University Jerusalem, has the following very pertinent lines:
"Fascism has no sound and obvious footing in any particular social class, and it's intellectual origins are in themselves confusing. In its most restricted sense the word
fascism refers to the political regime in Italy; at the other end of the scale, the 'fascist' epithet is used, and particularly by left-wingers of various hue, as
the term of abuse par excellence, conclusive and unanswerable." (My bolding).
To label all sorts of one's opponents as 'fascist' is unhelpful and misleading, which is why in the Israel thread I said I preferred 'criminal' to describe the actions of Netanyahu and his regime rather than the ubiquitous 'fascist' term.
In this regard I doubt if the little Englanders with their lovely artistic tattoos could converse for ten seconds about what is their actual ideology, other than thuggery, looting, and violence. Oh, and mindless hatred of anyone of a different colour.
Mind you, some of those hard men are so covered in tattoos that it is difficult to discern just what is their own original skin colour.
As for the idiots here in Ireland that have been rioting against asylum seekers and burning proposed accommodation centres, they would also be clueless in any attempt at political debate on ideology.
Again, violence and opportunities to attack the Gardai (police), as well as looting of innocent business people's shops, are all they seem to understand.
I certainly would not label them as Fascists or Anarchists as they wouldn't have a clue what those words really mean.
