Disagreed, but it's a personal taste thing. If they aren't fresh and crunchy I don't like them nearly as much. Same thing with spinach/lettuce/cabbage, broccoli, and cauliflower - they can be "cooked", but again it should be very lightly so you don't lose that fresh crunch/texture. Some of these things can be "OK" cooked a bit more, but I've never had any of these fully cooked in any way than is better than fresh or lightly stir-fried/seared.
IMHO, of course.
