If it was a deobandi Madarsa, then rest assured that no one in Deo-Bandi school of thoughts favors actions of Yazeed. Yazeedi Nara is just an excuse here to hide the facts. If Deo-Bandi school of thought favored Yazeed, we don’t have book ‘Khilafat o mamollokiyat’ written by Molana Mododi ( A Deo-Bandi scholar). The book is considered authentic in Shia circles.
