great post!!! the absolute Terror of elbows when Muay Thai first made its debut in America was extremely palpable... heck they wouldn't even allow you to knee to the Head and don't get me started on American kickboxing and it's Terror campaign against Muay Thai
People were so crazy they were even suggesting that Thais had a special racial advantage that allow their bodies to tolerate elbows better than Caucasians blacks and other types of Asians
Even my beloved K1 Nerfed down the Muay Thai rules in order to make the sport more culturally acceptable and here we are today in MMA where athletes are throwing hard core spinning elbows to each others face
it's entirely cultural and makes us look like a bunch of Nancy sissies because we're afraid of a technique the rest of the world considers standard
There's literally thousands of years of data associated with Muay Thai and overall it's proven to be safer than Victorian boxing!!!!
There's absolutely no difference in the concussive impact of a kick or a knee just because an athlete has got their hand or knee on the ground
The wrestlers and BJJ guys aren't terribly keen on it, that's for sure
