Yes, because being taken into a room and forced into the fade to face a demon with the alternatives being death or tranquility is such a picnic. The Templars do not know what it is to be harrowed or to have the threat of possession and tranquility hung over them in such a manner.

Just as mages do not know what it is to be the ones to perform the right nor to send mages to what might be their death. Nor is there a way for either side to learn the other. Moving forward must be done with all possible consideration to every experience involved in this; those that endured abuse, those that did not, those that swam through their harrowing, those that passed by the skin of their teeth, and those that never endured in in the first place. The Inquisition is to be better than what came before. Hence the open, public discussion and attempts to compromise.
