Not offended and I find it funny, though you nailed my itching:
> "Veganism is a philosophy and way of living which seeks to exclude—as far as is possible and practicable—all forms of exploitation of, and cruelty to, animals for food, clothing or any other purpose; and by extension, promotes the development and use of animal-free alternatives for the benefit of animals, humans and the environment. In dietary terms it denotes the practice of dispensing with all products derived wholly or partly from animals."
My personal take is yes, assuming there's no animal exploitation or cruelty involved.
That said AFAIK there is no consensus: some abstain from all animal inputs while others focus on avoiding harm, which itself can be interpreted in different ways. It's more a philosophy than a rulebook, lab-grown meat kind of sits in a gray area. I'd be curious to try it :-)
