Depends...
Most of them are idiots who never set foot on a Jiu Jitsu mat nor took a striking class, base their analysis on what they've seen, and generally have limited knowledge at how the sport actually works yelling at someone stuck in side control, "Just stand up, bro!"
The maybe 3% of that collective, have actually trained long enough to know what's going on, legitimately get excited because they can see the Kimura from Closed Guard coming, and can find other things that can happen.
Those are the ones who don't run their mouths constantly either.
That small group are also the last people you'd think who could literally break people like rifle in half, not even joking, all the muscle in the world can't stop hyper-extension, nor can any sort of bragging.
But that's what sets the sport apart from others minus maybe wrestling...you're going to start at the absolute bottom of the Totem Pole and have to work your way up...and these days, everyone is ego driven and can't take that.
Hence, why they quit.
Imagine an RN at Cabell Huntington being (at the time and maybe even now) the most skilled Brazilian Jiu Jitsu fighter and having the UFC submission of the year TWICE.
He is saving your life while also being capable of ending it:
