I know what you mean. It used to be a small niche where only the die hard MMA fans understood what it is and had the small family feel. Now that it's multimillion dollar company, you see everybody's mom and neighbors all wearing the Tapout clothing and the old timers kind of get turned off by it.
However, it's part of the business and you have to accept it. Just take the comfort in that all the money from the posers are still paying for the hard working MMA fighters.
