 You are quoting a book that is quoting an unnamed sources that claim milonguero style is the one true tango, then claiming all people that dance milonguero style say that.  Some uninformed idiots may say things like that, but that simply is not true for everyone that dances this way.  All you are doing is perpetuating trash talk.  Yes, Gustavo Naviera is one of the founders of Tango Nuevo (but don't call it that in front of him or he will say you are using the term wrong!).  He is also one of the strongest critics of milonguero style.  So what value is quoting his personal opinion where he insults the dancing ability of people dancing milonguero style?  These are ad hominem logic fallacies. 

 I don't even care about milonguero style.  It's just that your section really was little more than personal opinion and gossip, and is of little academic value.
