I am pretty certain James was not suggesting you "drop your shields".   
My understanding is he thinks anyone who -only- protects their own  
router CPUs, but lets random packets leave their network with fake  
source addresses for other networks is an ass hole (shields up or not).

Assuming that is what he meant, I agree with him.

Now, would you care to reiterate your ass-hole-ness and admit to 10s  
of 1000s of your closest friends that you let your users attack them  
(and me!) in undetectable ways, make things like the Kaminsky DNS  
vulnerability possible, etc.?
