More on and or

There is an interesting comment thread on reddit about my recent post about “and/or”. My favorite:

TL;DR: applying Boolean logic to linguistics is an exercise in futility.

Another commenter points out something I had missed:

Also, “/” does not just mean logical AND. Two counterexamples: “his/her”, “male/female”. In these cases, as with “and/or”, it means logical XOR. Applying that to “and/or”, you have (A AND B) XOR (A XOR B) = A OR B.
