Dear sir, but however , we should strive to achieve unity of all Muslim sects. Celebrate Muslim diversity , unity in diversity. Actually every Muslim sect has problems (because of Dajjaal ) :- Saudi islaam leads to september 11th attacks ( , etc., ) ; Barelvi-ism leads to shirk and biddat ; Sufi ism leads to idolatry and grave worship ; Shia ism leads to worship of human beings ; Deobandi ism leads to disrespect ; etc., etc., so we should strive to rise above these differences ....
