Earlier quoted context omitted.
Who says they are oblivious? Maybe they just don't like to hire people who don't drink. Why should they be obliged to hire them?
I never said they should be obligated to hire them. It is really inefficient to pick IT, UX, Sysadmin, etc. talent based on whether they drink or not. So I'm assuming they are oblivious.
Edit: re "religious" argument: surely you can get some non-alcoholic drink at a bar? Water, if nothing else?
