This is hard to understand. The party in power in the UK, the Conservatives, are overtly anti-EU and have called a nationwide referendum on leaving the EU. I don't see anyone talking about banning them or the many leading public figures are coming out for Brexit.
> in case you didnt notice, is conveniently conflated with "populist right wing parties" a la UKIP, FN usw
No, it's may others too, as I pointed out above. The parties you mention are actually populist, right-wing, and often racist and xenophobic nationalists.
> I see ... I see ...
To be clear, those are one person's predictions; nothing like it has happened. If any group is at risk of oppression, it's the Muslims and other minorities against whom many of the parties you list openly advocate discrimination.
