No, you are not over-reacting. But I see in a later post that the parish is led by the Jesuits. I groan to hear that. The Jesuit Order is very large, composed of members of an incredibly (literally unbelievably) “diverse” range of theological perspectives. I have known some very orthodox Jesuits - and some who brought anguish to me to be in ear-shot range of them. You would need to communicate your experience to the head of the Order - although the diocesan Bishop still ought to be contacted, but I’d expect he would refer you to the Jesuit head - and I doubt, if you contacted both men, that anything would change.
Also, I would advise you to be sure in conscience that you want - and ought - to do this. If you are morally certain that these practices are truly abusive to the holy Mass, then you can be strong in the conflict that you are possibly (probably) inciting. I’ll pray for you. It can be very discouraging not to be taken seriously, when you believe that the matter is indeed a serious one - hence, “be strong.” “Be not afraid!”
