I apologize if the topic has been discussed to any extent and I was unable to find it, I also apologize if I offend.. I am unsure about this question.

Speaking with someone I recently met, they said they were part of the American Taekwondo Association... upon research, it looks like a McDojo.. a really really big one... and I reapologizes if I'm wrong but how do you guys feel about them?
