Wow, what a great thread!! Here I was thinking I was the only one to pick out the celery from tuna/chicken/potato salads. My husband thinks I'm nuts, says you can't taste it...but I hate the feeling of bitting down on it. I'm also with you on the cilentro-- it has such a strong taste -- and I also can't stand pimentos. (Years ago, I use to almost live on Starkist Tuna Pot Pies, and have 'fond' ?? memories of picking out every single pimento before I'd eat it-- even though my Mom would try to tell me they were tomatos!)
(PS-- along with pimentos, I won't eat peppers -- or anything that had peppers in it)
