Is this how Americans views tough, real men?

I just watched some episodes of this show and I kind of like the whole 'we pretend it to be real' angle. It is funny at times.

I get these are supposed to be badassed real men, who live by some sort of warrior code. I get the whole a real man fights when it is absolutely necessary thing. I also get that they would feel it is necessary to defend their honour sometimes. But what I really do not get is that always when they beat up someone of the opposing gang or take his cut, they far outnumber that person. Afterwards they are saying they earned respect by doing so.

How is that the tough guy thing to do? How would that ever earn respect? And how would the person that has been beat up ever have to feel defeated against such an impossible force?

A 'real man' fights one on one or maybe group on group. But noone would ever view it as honorable or 'we got some respect today' where I am from when you beat someone up with multiple people. You'd lose respect, because you make it clear you were too scared to face the 'beatup-victim' alone.

How come they portray it in this way? Are you viewed as a tough guy in the US when you beat up single persons with the two of you? Do you then earn 'street-cred' or something?
