Some guy comes into a Holocaust discussion claiming to know a lot.

He doesn't know who Himmler is.

This is like claiming to know about American government under Bush and not knowing who Dick Cheney is.

Out of curiousity, I looked up what jobs one could get with a philosophy degree.

Strangely, this page had more than just "teach philosophy".

Hurlingham Club-Receptionist
The Bull Hotel-Bar Staff
The House of Agnes-Housekeeping Assistant
Thorley Taverns-Bar Staff
Topshop-Sales Assistant
University of Kent-Canteen Assistant
Waitrose-Customer Service
Wheatstone Inn-Waitress

But not much more.
