Why did someone tell me that I can't eat crabs if I don't like them?

I don't like eating crabs myself. Although crabs are easy to see at the seaside and the price is much lower than inland, I just don't like them. I feel like I have to wrap my shell for half a day, and then there are not many places to eat. I might as well eat some prawns or something and a pot of treasure chest, and then I can satisfy my appetite without much trouble. I don't think it matters what others say. Maybe some people think that you can't pursue quality life without eating crabs, but I don't think so.
