UFC isn't a sport though. It's (in my opinion) a place to go if you're too violent to take a normal job, and too bad to actually fight someone who knows what they're doing. (also known as Connor McGregor syndrome)
That's gotta be one of the most uninformed opinions ever posted on this forum. Everything you've stated is false. Every single thing.
I've done box, judo and bjj at gyms for some time, in different gyms, cities and countries.
I've hanged out on bars a countles times with all of the groups. I've never, not once, seen judo/bjjs provoke or look for a fight outside the gym. With boxers it was pretty much the norm.
When a boxer came bruised or with a black eye he was generally teased for it. It was seen as if he had lost a fight against a "civilian". In bjj/judo it was frowned upon and he was asked to explain himself.
The bjj crowd is very intolerant towards violence being used when not attacked. Incredibly intolerant.
A bjj practitioner is trained to immobilize a guy without (seriously) hurting him if he chooses to do so. That's what taps are for. A boxer's only way to stop a fight is through a ko or through intimidation. Both tend to act accordingly, which regardless of right/wrong, makes sense.
And, just to be absolutely clear, you take a random guy with 2 years training in boxing vs the same guy with 2 years training in bjj and the latter would kill him 99 out of 100 times. I dont mean figuratively, i mean literally.
Someone like you would probably look at it and think, "ohh, he landed on top and the boxer twisted his ankle/knee/elbow" and attribute it to luck because, well, you dont "know what they are doing".
Bjj is not about aesthetics, it is 100% about effectiveness. To the untrained eye it will look unappealing, boring, even nonsense. Thing is, it's the closest thing you can get to a superpower (fighting wise).
The difference between two people roughly the same size if one is trained in bjj and the other isn't is nothing short of abysmal.
You have a better shot of tackling Lomu at his peak than beating a version of yourself with a year of bjj training.
