Frosh year there was an active Muslim guy in my dorm who I talked to on occasion. And he got angry at the way I pronounced “Muslim”. It sounded like “Muh-zlim”. And he was pretty angry about it, so ever since then I’ve been really careful to pronounce it like “Moo-slim”. That’s probably still not completely accurate pronunciation, but yeah, it’s amazing to me, how this one incident changed my behavior forever.
