Not the person you're responding to, but I think they mean they're non-(vegetarian/vegan), so both not a vegetarian and not a vegan.

And I do get them on liking black bean burgers but not liking the impossible burger. Black bean burgers aren't trying to imitate a beef burger, they're trying to be an easy way to put black beans on a burger bun. On the other hand, if you want a beef burger and are handed an impossible burger, you might be disappointed because they're not the same.

To blatantly put words in brognak@lemmy.dbzer0.com 's mouth: "Eat meat if you want meat, eat veggies if you want veggies, eating veggies disguised as meat leads to a mismatch of expectations which leads to disappointment."
