Mixed Martial Arts should be taught in school from an early age.

Training MMA means doing exercise which is always good. However I would word this premise as "Universities/Schools should offer MMA classes" rather than this current premise.
That doesn't change what I said at all. To add new material, one must remove current material. Even if it's removing similar material, that doesn't change that it's a zero sum game (in terms of quantity, if not quality).
Not exactly. MMA incorporates already used exercises or can be made to. Technique would just need to be improved. Quality MMA could replace the quantity of poor exercises. Games like dodgeball could be replaced with MMA.
Games like dodgeball are used to keep the students from getting overly dissatisfied. Take away dodgeball and you'll have a riot for the first few years at least.
Not true. Someone can be strong in mainly one technique and take out someone with stronger technique in other areas. Even if you are trained in MMA, If you know someone else has also been trained to knock or choke someone out, you're less likely to pick a fight with them.
