Depends on the policy.  Zero tolerance can be a good thing.  For example, a zero tolerance policy towards pedophile priests would be a good thing (a real one, not some lie told to mollify public opinion).  On this, of course, we disagree, as you have always been an ardent supporter of clergy regardless of what they are doing.  But zero tolerance policies in schools have often resulted in ridiculous and damaging results for students, regardless of their color.
