> Given that European countries and the EU except a few outliers runs on proportional representation it is way harder for the extreme right to win a majority.

Harder, but it still happens. That's why Trump is a big fan of Viktor Orbán and his Fidesz party:

Fidesz won a supermajority in the 2010 election, adopted national-conservative policies, shifted further to the right and became Eurosceptic. The 2011 adoption of a new Hungarian constitution was highly controversial as it consolidated power with Fidesz. Having set Hungary on a path of democratic backsliding, its majority of seats remained after the 2014 election, and following the escalation of the migrant crisis, Fidesz began using right-wing populist and anti-immigrant rhetoric. Following the 2022 Hungarian parliamentary election, it currently holds a majority in the National Assembly with 135 seats. It has also held the presidency since 2010, has endorsed the election of every president since 2000, and it enjoys majorities in all 19 county assemblies, while being in opposition in the General Assembly of Budapest.
