I practice Karate and I’ve trained in dojos world wide and everywhere it’s the same, everyone is super down to earth, humility and respect are baked in and I’d be extremely surprised if any of the practitioners (at least the higher level belts) would be racist, let alone a Nazi sympathizer, as you always work and train together with people from all nationalities.

There is a huge amount of respect for other practitioners, there is simply no space for hatred over nothing
