Joe, quiet, rational and dispassionate is not always appropriate: when one's friends, neighbours, loved ones are being called vile things, denied a fair and equitable place in society, legally prevented from pursuing harmless activities, subject to violence because of their very existence; this is not the time to pretend those in opposition are capable of hearing quiet reasoning. Sometimes it is right to be loud and angry when opposing bigotry.

I do agree that shunning can be effective, if the haters are small in number, and certainly within a Mudcat thread, shunning could work well.
