greetings ,
i&i think that first i would liketo tell you to clarify what you mean by white "rastas" as it seems like you do not think that could ever be a rasta who is white in skin color . puttin rastas under caps make me sense that is like dem a joke , so no disrespect intended here , i'm askin before answer your question just to see if could have be a positive reasoning .
Cause like this , you are comin with half truth it seems , like want to reason wiht people which you call "rasta" but you no think they are ...and more you are expressin it , so.
i hope you got my point , again no disrespect intended ,

peace
