to post or not to post

a friend of mine sent a link regarding some wanker who is spewing forth hate. since he is not really known in this country (and probably not even out of his own country), do i post this information? is it aiding and abetting this wanker, giving him publicity he does not warrant? i don't want to give this nonentity the time of day, but is it my responsibility to out him and his ilk?
until i resolve this dilemna in my own head, i will post a pin up for your edification.
