Apart from gelatine, which even as a muslim I never avoided (something about a "law of change"...or something), I've never had pork. I became a vegetarian shortly before I left Islam though.
I only had pork once accidentally in a restaurant, and it was called "City Chicken". Anyways I turned vegetarian later.
Do ex-Muslims eat pork eventually? Not if you're vegetarian.
I see there are not so few vegetarian ex-muslims. And I'm not surprised. Because if you become an ex-muslim, that means you are usually someone who
thinks and is not afraid to reconsider his previous beliefs. And that makes one more likely to become vegetarian imho.
Save the rabbits
