Thx for busting me up this morning!

But what you say is not strictly true. When the RTT goes way, way, way
up (as in email) it becomes much more possible to have an unresolvable
heated argument that cannot be shut down down without invocation of
godwin's law.

Short RTTs (as in personal meetings - and perhaps, one day in a more
bloat-free universe without annoying jitter), make it both more
possible to have a heated argument... and a resolution.

A shared beer, helps too, also. :)
