A person needs to make a statement about their core and the core of their MA:
Is it about fighting or something else.
Every MA was developed with fighting in mind as it's core (sometimes as it's only goal) and to turn our backs on that core is to deny tradition.
MA were also developed, typiclaly, to deal with OTHER MA/fighters and not just "the layperson" and, IMO, that is where many TMA have "dropped the ball".
The view that "what are the chances you will fight a trained fighter on the street" is, IMO, the worse possible mindset to have.
Psalms 144:1
Praise be my Lord my Rock,
He trains my hands for war, my fingers for battle !
