I was being facetious but you are agreeing with the point that American kickboxing is ineffective - you’re just elaborating on the why.
it shouldn’t need to be said that these “effective/non effective” bold generalizations only apply to elite levels. I am a huge Muay Thai enthusiast and I love to train little variations of the mt clinch and perfect my shin blocks and my balance and all that stuff but still any legit shiny pants amateur fighter with a couple fights experience would whoop me with little effort.
Honestly I don't want to get into that but I would not say that shiny pants is ineffective. It has boxing in it and all sorts of kicks, all of which is full contact. I mean if shiny pants is ineffective, then so is boxing. I think it's all relative to the ruleset. From my perspective, any combat sport which incorporates no restriction on boxing has its place. Likewise, kyokushin as an example also has its place since it is a very good full-contact kicking art, but the restriction on punches make it incomplete. I would not say that kyokushin is ineffective, even if it is not complete. Some arts need adaptations, just as long as they are legit in their area of specialty, and both shiny pants and kyokushin, which I bring up, fit the bill.
Some martial arts like animal kung-fu, shotokan and all the ryu karates out there are largely useless, though, IMO.
If you remember Dennis Alexio for example, that guy was an absolute killer with pretty good boxing, but is a shiny pants fighter.
Lastly, and I know that this comment will not be appreciated by many posters here, but I think that a current form of MT, which is currently prevalent in the stadiums at the highest level, is drifting away from what MT used to be and is starting to look like TKD a bit, with all the arm kicks spamming with the purpose of winning on points. But I digress.
