Holier Than Thou is built into all religions? What an odd thing to say. If you mean that they all think they’re right...well DUH! If that is your definition of the phrase, I would have to say that virtually all human groups have that built in. Republicans? Democrats? Mother’s Against Drunk Driving?
Why would you belong to a group (or believe in a religion) that you thought was wrong?
