I don't know there will be any "losses through argument". Sometime ago I competed in a debating contest. The subject was "Is individual more important than the country, or is the country more important than the individual?" No matter how deep that I might get into that argue, there would be no winner and there would be no loser. The same will apply on MA discussion such as:
- Is striking superior than grappling, or is grappling superior than striking?
- Is TMA better than MMA, or is MMA better than TMA?
- Is "sport training" better than "SD training", or is "SD training" better than "sport training"?
- After you have thrown your opponent down, should you remain standing, or should you follow your opponent down to the ground?
- Should you train slow, or should you train fast?
- If you have solid MA foundation, can you learn from video?
- Which MA style is the best?
- Should you develop technique on both sides, or should you just develop your technique on one side only?
- ...
For example, if you like to develop technique on both sides and I like to develop technique on one side only, through the discussion (or argument), how can you make me a loser (or the other way around)?
IMO, all those discussions are just look at the same subject from different angles and there will be no right and wrong answer. So there won't be any "losses" through discussion (or argument).
Then what you are citing is the usual thread directions with grappling, striking etc. A,B,C and D go through the same stuff with the same old stuff. Arguing a point has to have a loser, except in this case the loser learns and updates their knowledge base. Not the same old grappling, striking and TMA content never evolves beyond starting threads with the same old!
