There is nothing you can do about it with words. I dont even train at a 10thplanet school anymore because the one near us changed affiliation but I still get shit at my own school and others for some of the techniques. I personally make it a point to tap each of them out with the same techniques they call bullshit and low percentage over and over again. What I have found is that eventually they start to respect it when they are constantly being defeated/submitted by it and most of those guys come to me and ask questions now about how to defend and even how to utilize the techniques themselves. Running your mouth is one thing but backing it up and doing it live is another.
I have nothing to say to these people anymore. If your style is better than prove it on the mat...period.
Its like Joe said...you cant fake this shit...on the mat...you are what you are....your words cant save you in the shark tank. Prove them wrong on the mats...one by one....thats how I do my talking.
