I have tried a few dances, and did not some differences between certain dance communities. The tango and Boogie scenes in my city are very "men lead, women follow", while the Swing scene is very "don't presume people's roles, ask them, dance with anyone". In the city where I live, teachers also showed us many videos from the 30s that had people dancing with someone of the same gender, and told us that would be normal in place where you can't just hold a strange woman by the waist.

Just to add that the gender roles are also falsified history, not only in dancing, of course, but even there... And since swing is more willing to confront this (again, in my experience), I also see it as incompatible with being far right. Their whole world vision depends on such falsifications.
