So, from now on, Gypsies should have to do what they are not built or born to do and stay in one place? Our traditions would be a lot poorer without their contribution, and I'm not just talking about my mother and the generations before her. Tradition just does not work the way that you think it does. There are great and ancient nomadic traditions in the world that would be lost under your rules, traditions that rely on constant change, reinvention, the passing and integrating of new blood.
Our traditions do not spring from a single source and would not survive were they reduced to one.
As to where you should learn material from that's up to you, there's a whole world of research material out there for you to find out about; a man of your academic bent is no doubt eager to root it out for yourself, use it to its fullest extent and glory. You are by no means done yet as I'm sure you know. You do, don't you?
But you would just do yourself so much of a favour in your endeavours by exhibiting even the tiniest bit of grace. Now I'm erasing words that I really think and trying to be nice to you again. Time for bed.
