For me it's anything involving cars or horses, also american football, and sumo, how about anything in general that intentionally harms the players health just by playing?

Martial arts are perfectly fine. If you actually mean MMA as a combat sport, it gets much more complicated. I don't think people should intentionally give each other concussions or break each other's legs for money. MMA training on the other seems like a fantastic work out.
