"They'd have a point. "
Perhaps, if IPv6 boxes didn't usually automatically firewall the internal lan in the same way that IPv4 NAT boxes do by accident rather than design (and ipv4 NAT boxes don't protect against internal systems being Pwned via whatever reason, then making outbound connections to find new victims)
Of course if you want to connect anything to the Internet without some form of firewall out front then you're a braver person than I am. If you're sensible you firewall outbound connections as well as inbound. That's the difference between putting up a filter and ensuring you're not contributing to the pollution in the first place.
