Pope John Paul II had a great interest in reforming the Liturgy, but remember all of those crazy Masses he had to endure? There are committees responsible for such things, and if then-Cardinal Bergoglio didn’t take action, it might be because it is quite difficult to address everything, especially when you are out serving the poor, and some other person or group has been designated to take care of planning Youth Masses.
Youth Masses and huge outdoor Masses are not the norm. Don’t judge him by things that are the exception to the rule. It’s not like he okayed this kind of thing on the parish level!
