Yeah, true! But if you are standing on concrete or something else hard and you knock someone out cold, they will fall flat and problably hit the back of their head real bad. Same thing with takedowns... They can hurt one even more as it's the bodyweight of 2 guys landing on one head in most situations. Mounting someone and raining down with elbows is nasty as hell! They get alot of cuts and teeth will fly... damn man! That's nasty stuff, esspecially when someone totally out of their mind doesn't stop punching the other guy... Watch Pat Smith at UFC 3 or something like that.
Fighting without gear is always dangerous. Someone will get hurt, real bad! And unless someone totally has it coming I wouldn't hit them. But in some situations it is unavoidable. Like the time I hit that dude, I was drunk and talking to someone and he sucker punched me. Those kind of people really have it coming. But otherwise I don't do street violance.
