What don't we get?

Our children weren't raised since infancy to hate those not like them and kill those who dare to think differently.  Why now are our young people behaving this way?  Is there some flaw in our child raising abilities?   Has the world and have young  people always been this susceptible?  Perhaps to a minute degree but not to the majority or there would be rioting and warfare all the time.  Can we do anything to change or stop this insanity?  Neither Dr.s, behavioral counselors, or even parents seem to be able to come up with any solutions.   How then can this crucial problem be solved?  We need answers.  Now..................................marge
