Think Mike Tyson's fists will become useless and he wouldn't know what to do if someone attacks him .... should he one day decides to wear all of this gear on and becomes a mall ninja?
You are again comparing apples and oranges and then coming up with advocados. To begin with, Mike Tyson was a boxer. I've boxed before and my grandfather was Golden Gloves. I don't remember that training going into cover and concealment. I don't recall it covering escape and evasion or door entry, room clearing or the fatal funnel. As I remember, boxing covered the jab, cross, uppercut, bobbing and weaving and various other applicable subjet matter that dealt with the rules of boxing. And, in a boxing match the opponent is doing the same thing. Not much chance he's going to pull a knife on you or a gun or improvised weapon. Not much chance his buddies are going to jump in either. A boxing ring is a flat, padded, level surface that is dry and well lit. It also comes with a referee and corner men. And of course you have a minute break every three minutes. The battlefield (or the street) comes in all sorts of user-unfriendly environments from sloping landscape, slippery, muddy, wet, hot, cold, snow, rain, dim or no lights and enemies that don't follow rules and want to kill you or cause you as much damage as humanly possible in as short of time as possible. So once again, boxing, or MMA, or sport TKD or fencing etc are great for the venue in which they were designed but have very little to no carry-over into the battlefield (or street).
Certain elements can be used but again they are limited. For example, using your boxing example; boxing is great in the ring, when your hand is wrapped and you're wearing gloves to protect them. But punching someone in the face with a bare hand in the battlefield (or street) isn't the best option for a variety of reasons. First, the chance of self injury is high, particularly when punching the head/face. Injuring your own hand limits your options i.e. using a cell phone to call for help, handling car/house keys to escape the situation, address possible injuries, further defend yourself, access improvised weapons, manipulate a firearm (loading, reloading, clearing malfunction) etc. Secondly, the head/face bleed pretty freely. If you've injured your own hand and bleed your attacker you now have to be concerned with blood-borne pathagens. This is a bigger hazard than people realize! An attacker is by definition a bad guy. Bad guys spend time in correctional facilities. Correctional facilities have a higher incident of stuff you'd rather not have. These are very real considerations. Thus utilizing boxing skills outside of a controlled environment isn't the best or most suitable option. As the old adage goes, 'if all you have is a hammer then everything looks like a nail'.
Also, boxers tend to wear very loose fitting shorts and are warmed up and stretched out prior to engaging in their sport (at a pre-appointed time and place). Soldiers on the battlefield (or officers or citizens in the street) don't have that luxury. We tend to go from 0-100 in the blink of an eye and have to deal with possible adrenaline induced physiological responses i.e. tunnel vision, auditory exclusion, flinch response, OODA loop etc. Sport training doesn't fully (if at all) address these aspects of critical response training. So while Mike Tyson is/was a great boxer and puncher in that environment, put him in full battle gear or what I wear on-duty every day and then have something kick off eleven hours into a 12-hours shift and have him ONLY use his boxing training and he'll be at a disadvantage. There are better options and better training.
I dunno. Maybe your young? Maybe you feel picked on here? Maybe you feel you're backed into a corner? Maybe a combination? My advice to you is to simply chill out a bit. Consider the possibility that you're wrong. You have people here that have done MMA telling you that you're incorrect on many/all of your offerings. You have people here that have done things in real life that most have only seen in video games and on T.V. telling you that many/all of your offerings are incorrect. Maybe...just maybe we're right and your not. Perhaps, instead of sarcastic remarks in return, you should carefully consider what has been said to you and learn from it. Enthusiasm for ones art or MMA is commendable. But being open to what it is, what it is not and the experience of others is more commedable. Being friendly and showing a willingness to learn from others is wisdom. Tossing back sarcasm is simply a quick way to getting booted from the board. No one here is your enemy...so don't make them your enemy. Be open and learn. Your choice.
