You guys are misunderstanding drop bear's point entirely. He is not at all claiming that TMA practitioners are unable to defend themselves because they practice indoors without shoes and so on. He is saying that some RBSD practitioners have made that claim and that he thinks the claim is complete rubbish.
(Drop bear - if you could spend a little time adding actual punctuation to your posts it might reduce this sort of confusion. This isn't the first time people have thought you were making a point that you were actually arguing against.)
Ahh...well, in that case, I owe you a thanks for the clarification and an apology to DB.
