I was given this same directive as a hemophiliac child. To give you an example, I can bleed internally if I tie my shoelaces too tight, so physical attacks are much worse for me than the average person. When bullies assaulted me I was told I must turn the other cheek so they may hit me on the other side like Jesus, not run away or defend myself.
When I defended myself once, the bullies stopped but I got a severe beating for disobedience to the bible.
Okay, not defending the bullies or bullying, but at least the bullies probably didn't know how serious it was to your health to be physically bullied... but your parents did. And the fact that they beat you for defending yourself from attack, or even demand that you allow others to physically attack you, knowing full well your situation, makes them criminally negligent.
Bullies need a good ass kicking, parents like that need to be locked up and have parenting rights take away.
