I agree with everyone who says to reject this amendment.  I understand the desire of parents to protect their children, being a mother myself.  But this is definitely a slippery slope.  There is no way a teacher can know ahead of time what might or might not offend a parent, and frankly people are too easily offended these days.  Not to mention too many try to shelter their kids way too much.  I have worked in higher ed and seen the result of parents over-sheltering their children who can't even function in daily life without having a nervous breakdown.  I am not exaggerating.
