The haters have no intent on trying to find someone that is good in traditional martial arts. This is a yearly lei-tai event where martial artist from different fighting systems fight each other. There are others like it around the world, but no one has ever used these guys to prove that traditional martial arts sucks. It's always pick the guy who is the worst at something and then claim that everyone who trains the same thing is just has horrible.
I've sparred amateur MMA fighter, boxers, and amateur Muay Thai fighters and they never walked away thinking I suck. Most fighters tend to spar with those who are on the same level or on a higher level because they are looking to either maintain their skills and get better. You can't improve by always sparring against people you know you can easily beat.
I was challenged by a "celebrity" TV show host who wanted me to fly all the way to china to fight him, so that he could prove that he could beat me up. What kind of nonsense is that. So I flipped it on him and told him. That he was weak minded. If he truly believes that he can beat me so easy then why would he want to fight me? That's just being a bully. If he wanted to fight me because he thought I would be a good opponent. Then he must think my martial arts training is good enough to fight against him, which in that case, there's no need for me to take a long trip, spend my money and time to meet someone I don't know, to prove such an insignificant thing as "my martial arts training doesn't suck." I told him he was either a bully that preyed on those who he thought were weaker or he admits that what I do is effective.
Fighters in general always try to prove themselves by fighting upward in the ranking and not downward. Anyone who brags about fighting someone they know they can easily beat is trying to prove to themselves that they don't suck, but at another persons expense and risk. The key is to not give people like that any validity. The "battle" with them is not a physical issue, it's a mental one, so beat them mentally without trying to prove what you can do and they will quickly fall away.
