So, PETA can fuck the fuck off, in a nutshell. You're not a true feminist if you leverage female objectification for your pet (no pun intended) concerns either.
On a side note: last year, I incidentally (i.e. without knowing; I'm not in the habit of exploring applicants' dietary choices during job interviews) hired a vegan and caused temporary departmental panic when the facts transpired ("OMFG, we're never going to be able to do team dinners ever again, are we?"). The vegan in question turned out to be lovely and, basically, just not an arse to everyone else and all her colleagues adore her at this point. So, PETA, you're giving vegans a bad name for no reason!!!
