Inspired by this question, that is a kind of a guide to "diplomatic relations" with non-veg*s, I'd like to ask what could be good answers to the oft-repeated assertion that "plants suffer too".
The dialogue goes roughly like:
A: "ok, so you're vegan, why?"
Me: "I want to avoid animal suffering"
A: "you're wrong, since plants suffer too"
How do you answer to that? How could you communicate that the respect for animals is not detracted from by the fact that plants show response to external stimuli?
