From a British perspective:
Mainstream Party: Tories (pretty obvious as to why)
Minority Parties: Patriotic Alternative (links with proscribed neo-Nazi organisations that have recently been sending extremely racist and transphobic death threats via letter)
Left-wing Party: CPGB-ML (TERFs)
Out of every strategy game I’ve played, HOI4 just eludes me. Can’t do anything in that game despite spending ages watching pros and reading different tutorials. It’s a shame because it’d be fun to experiment with alternate histories, but alas.
TERFs are far-right at the end of the day.
