More politely stated, it’s not the responsibility of the operator to decide what belongs on the network and what doesn’t.

Don't most residential ISPs already block port 25 outbound? http://www.postcastserver.com/help/Port_25_Blocking.aspx Blocking chargen at the edge doesn't seem to be outside of the realm of possibilities.
