If someone is offended by this joke, maybe that's a sign that they're uncomfortable with the modern mass production of meat in general, and they'd be more comfortable within themselves if they ate less meat.

Yes. It's not possible to respect these lambs or consider yourself a friend to animals while looking forward to eating them. Not without playing tricks on your mind. The definitions of friend and respect simply don't allow for simultaneously accepting a cruel fate.

I am vegetarian (and striving to make more vegan choices day by day)

Walked the same path. Vegan for just over a year now and no regrets. The benefits outweigh the downsides.
