You have every right to not want to explore this stuff. It is simply your decision. You have heard from numerous people who have clearly articulated the differences in the "IT stuff" and pointed out that if you have not put your time in directly with this stuff, you really do not know it (and therefore cannot do it). You can pretend that you can do it, but you simply stand out as the prince without his clothing on. You can pretend that it is all nonsense and you still act like that same prince.
You have been offered opportunities to experience some of this stuff first-hand and you do not want to have to put your words to genuine reality tests. That is fine as well, because it is simply your decision. I would just respectfully request that you simply stop with the negative comments about things that you do not really know about and do not want to find out about. That way, people can continue to discuss aspects of an art that you do not believe in, want to do, etc. without having to digress to address your overly-testosterone based perception of your reality of things.
Marc, I know what I know and that is good enough for me....
When I see these people in the ring/cage up against a real fighter who is not going to collude with this nonsense, abide by no rules, put their money on the line, then I will believe it.... until then......
