All Muslims should come together to the Ahlul Bayt (as). Their path is the Sirate Mustaqeem and their love is the wage of Risalat and is demanded by Allah (swt). The Prophet (saww) said "my Ahlul Bayt are like the arc of Noah (as), for whoever takes refuge in them, finds salvation".
No muslim can say that he does not follow the Ahlulbayt, but while u say ahlulbayt gave a new fiqah , others say that they did not and their teachings can be folowed by following the other fiqahs.
So 12ers have no monopoly over ahlulbayt
