    The internet will be better without ISP refusing to apply BCP38.

    This is a pointless argument since the majority of the industry
prefer going after the <flavor of the month> UDP flood instead of
curbing the problem at its source once and for all.

The Internet will be a better place with less open resolvers around.

You are going to have to change your mind about this one. Open recursive
resolvers are a really bad idea, unless you can afford a lot of time and
cleverness to manage the abuse. Get your users to choose a more
appropriate name server, and restrict your name server to your local
networks.
