Do you wear any boots? I used to wear a set of steel toed boots, a kick in the leg scares the little punks away. Do you dress really nerdy with your head down or keep to yourself? That makes easy picking, kids with low self esteem are easily tormented by sociopath jocks who have nothing better to do than get a thrill out of their friends by picking on kids who can't fight back. If you make a stand, shows you aren't backing down. People have this horrible image of Jews being the bookworms who become lawyers and doctors who can't fight, do you want people to think of you that way? Sure you might lose a fight or two, but what have you got to lose? You can claim self defense if they took the first swing, the school wants to threaten you with any consequences, threaten legal action for violating your civil rights and self defense, the last thing a school needs is a civil lawsuit on their hands over self defense and the media loves that kinda stuff.
