Why do you feel the need to tell people that the park creator is a nationalist? It is not a crime and the park is about history and entertainment for families and kids on school trip.
I don't think it will be a surprise to you that people creating and managing companies take an active part in the company's vision and direction.
Just like medias owned by far right or far left entities will put a far right or far left spin on everything they treat.
I never said it was a crime, I'm just saying that the park creations shouldn't be interpreted as factual nor accurate depiction of historical events.
It's like arguing that Jesus did XYZ because that's what you saw in the movie "the passion of the chirst". As I said in another comment, as long as you don't pretend you're providing historical facts it's all good, but it's not the case here.
You don't even have to go that far. It's obvious that the intention of the company's creator are carried through the company actions, be it nationalism, environmentalism, religious views, &c.
All sources are biased but some are more biased than others. Nationalists are the last people I'd trust to give an accurate depiction of their country's history.
You don't meet this guy when you visit the park. The park is an artistic endeavour to let kids and families learn about some french history in a fun way; the same history that you find in school textbooks. No politics involved.
