Ah...you are correct, my confusion is that of the other guy. And I agree, not a fan of the other guy.Yes, there does seem to be some confusion on your part, and nothing to do with your use of the second person ("you") in the general sense. Please read post #16 above by MTW for clarification. He points out that Rokas made no claim to have knowledge of every style.
BTW I think you may have him (Rokas) confused with "that other guy" i.e. some other YouTube commentator. ....Maybe that bearded idiot who trashes all TMA and started his own style of MMA-TKD (which looks pretty pathetic). Honestly, I don't remember his name ...and don't really care to!
