“mw13, as in the past. I am NOT going to argue with you for the sake of arguing.”
And I will not argue with you just for the sake of arguing. I will, however, argue with you for purposes of reaching the truth. Actually, I must admit I’m slightly offended that you seem to think I’m just goading you on – but that is certainly not the case.
“YOU ask your RAV what the meaning of massering is and if it ONLY applies to goyim.”
Actually, I never said that mesira is only by a goy, since I’m not sure if that’s true. I think you’re confusing me with Chein.
“My parents raised me NOT to masser on my siblings, friends or anyone. That is the proper thing to do.”
With all due respect, how your parents raised you and what you feel the proper thing to do is does not change the halacha.
In High School my principal punished the “snitch” for massering.”
“Snitching” for the sake of snitching might be massering (depending on whether or not messira is applicable by a Jew), but I’m pretty sure that telling a parent/teacher about a problem their child is facing with the intention of helping the situation is muttar.
