I didn't say that Bjj was the only art that trained chokes.Firstly, BJJ is not the only art that trains chokes. Secondly, legislation around the world now puts you at risk of prosecution if you use a choke, regardless of the outcome of the persecution.
And any one of my yellow belts also has the knowledge to choke someone out and break joints. Is that meant to prove something?
Its a pity that people in your school don't compete. A yellow belt in your style being able to choke and break limbs on the level of an advanced Bjj practitioner would make a fortune in the fight circuit once they reach black belt level.
