I’m going to keep using the words meat, meaty, to describe the main part and/or texture of the plant until such time that meat = plant.
I will never, however, refer to a plant as an animal – or an animal as a plant.
Plant chicken, yes. Because that’s what some brilliant people were able to make a plant taste like. But a chicken will never be a plant.
A plant is a plant and an animal is an animal. Right now, meat can mean either animal or plant. Eventually, and that day will come, animals will no longer be considered food on this planet, so the term meat will refer to the main part and/or texture of whatever plant is under discussion.
