Great, another "Gosh, what's the difference from eating steak?" doofus.
We need to get over pretensions of "the distinction is nonsense". The bug-eater proposal is not a suggestion that we eat wee little fillets of insect muscle. It's a suggestion that we eat whole bugs – shells, heads, eyes, guts, everything.
How often do you eat ground cow? No, not ground beef; ground cow? Heads, hide, bones, hooves, guts, and all? You never have and never will? Exactly.
I'm not saying we need to balk at eating animals whole when it comes to bugs; after all, many people *do* eat insects, as you say. But for those who'll need persuasion to get there, let's not pretend that bugs are like teeny chuck steaks or dot-sized lobster tails, and sigh "get over it" when people aren't fooled.
