Almost, it is more that I don't care specifically why a IPSec option is often a liability, and would rather stick with something less silly.
Ad hominem attacks do not change the fact there are new issues in IPSec/VPN approaches found regularly. Pick any failure mode(s) on the list that applies to your specific use-case and platform.... or could find new ones if you are still bored.
