Seems like education-washing
The museum is funded by a combination of private money and local public education subsidies, but it is not in public ownership.
Everything depends on how they actually tackle that topic in their exhibition. You could absolutely criticise whaling while being in a country where whaling still exists. That museum would be a great opportunity to get public attention on the problem. Nobody knows though if that is the case, since it is not even open yet.
Everything else aside, duels were basically always linked to ‘honor’ and the accompanying societal pressure. As soon as you get duels back on the table as an option for ‘conflict settlement’, your ‘consent’ is very much under pressure by the societal expectations.
People in the past did not go duelling because they really liked duelling or wanted to die, but because it was the only way to reclaim your ‘honor’ in society. That is really not a culture anybody should want coming back.
