Mmm, a technique you need to work on is communicating properly, no one is dumping on you, they are reacting to your perceived arrogance in thinking you know more than people who have, collectively, been training for hundreds of years, who are senior instructors and even founders of styles. We have serving and retired military as well as serving and retired police officers (some have been both) on here, there's professional security people, bodyguards, MMA and full contact kick boxers, prison warders etc etc basically a lot of people who know about violence and you seem unwilling to listen to them.
If you are going to behave like a stroppy toddler telling people to shut up then any 'rude' replies you get are on your own head. Try tact. Tact is the art of telling someone to go to hell in such a way they look forward to the journey so please play nice, we'd like to hear from adults not children. This is the way.
