Four pages of people telling you "you ain't the MA police" and you still don't get it. Yes, there is rubbish being peddled to the uninformed. Yes, the bulk of MA training probably isn't truly combative. Nothing you've pointed out is revolutionary.

Any unprovoked criticism speaks more to the insecurity of the critical than the validity of the criticism, for me.
