It's gotta be a carve out for striking sports or something. Because me doing BJJ against an Israeli is as much an endorsement as playing pickleball with them. I also think those niche combat sports like MMA in a car are a bit too silly to not object to competing with an Israeli. But Olympic judo would have a solid case for not pulling out despite no striking (while pulling out would be intensely based).

I propose bare knuckle boxing to be the standard by which combat sports are judged as the minimum intensity threshold that a combat sport must overcome in order to be a better option than objection. If it's more intense (Olympic judo, regular boxing, kickboxing, MMA, HEMA) then you're good, but if it's less intense (BJJ, car MMA, fencing, novice judo) then it's less admirable. You ask yourself "Do I stand to do more damage to my opponent than a fist to the face?"

That satisfies what @小莱卡@lemmygrad.ml @FALGSConaut@hexbear.net @jack@hexbear.net were saying.
