I was being sarcastic about saying Mi K’amcha Yisroel. Due to the fact that learning and living Torarh is supposed to lead to behavioral refinement and sensitivity to your fellow man. Instead these “Torah institutions” choose to close ranks and keep out anyone and everyone with a tiny black mark on their record.
Kids will pick up on the fact that this system is a joke. I would not be suprised if your son follows in his brothers footsteps but maybe instead of just hanging out with other “undesireables” he will take his talents elsewhere and thrive in a less “exclusive” enviroment.
