That's bizarre and I don't think we've gotten anywhere near that point in Denmark. The right-wing parties in Denmark generally do not lot overlap fully with a Trump type agenda. For instance, we can have a party that is strictly anti-immigrant (anti-Muslim essentially), but then be very pro welfare state. On the other hand, the most economically libertarian party do not necessarily focus heavily on the immigration topic. It's one of the benefits of a system with many different parties.
It's completely bizarre. The AfD is running an agenda that would be devastating for its voter base if seen through. In terms of system, we have many different parties. I think the issue is rather that the voting process doesn't really feature a mechanism that allows you to vote the lesser evil like the second voting round in France. Personally, I'd favor a system in which every citizen has 10 votes and he/she can cast them for and against a party as they please. It would prevent parties from drifting into extremes as we are seeing it right now.
And we need to pay more attention to facts und science. Put that's also a cultural topic. Luckily, Meta has just announced that they ditch the fact checks and replace them with "community notes" so that whoever has more supporters speaks the truth from now on
