Very Important discussion.I would like to submit that
1.It was not founded by Imam Ahmed Rida Khan Quadri.He never founded a so called Barelvi movement.He was a one of the great Scholar of Sunni Sufi movement in South Asia.His opponents gave this title Barelvi.It was never used by him.He never said that this is Barelvi movement.He always considered his organizations and Institutions as part of Ahle Sunnah movement.Even today all organisations and associations subscribing to traditional ideology of Ahle Sunnah Wala Jamaah in South Asia just uses title of Sunni.In reality and on ground Barelvi word is not used by Supporters of Ahmed Rida.His opponents used it to fulfill their agenda that it is a new movement.
2.This seems to be doubtful.It has been contested here by Shabiha, you should try to support your view from more verifiable sources.The movement was not Madarsa based and this is just an allegation with out much explanation.
3.There is no such major linkage as you have tried to put.
4.I think it is very much in the Article.
I will share my opinion when other points will come.
