What are you even trying to imply here? Are teachers supposed to indoctrinate their students in your world view? Are you saying we can't judge what they do because we're not teachers?

When you're at a 5 star restaurant with people and the entire table says that the food tastes like shit, do you hush them by reminding them that they're not a 5 star chef and that they simply do not know what good food is? What are you trying to say?
