I don't care what you eat or why, but:

This is being fussy as an eater, and there's really no reason to try to redefine words to pretend otherwise. This constant desire to reshape the English Language just to spare some niche group of people ever having to hear any words that might have a negative connotation needs to stop.
If you're like this guy, just acknowledge that you're a fussy eater by normal standards, and either learn to be fine with it or figure out how to change.

If your psychological or physiological condition severely limits your ability to partake in life experiences as fundamental as eating a range of foods, that's a problem and not something I would promote or celebrate in any way. You aren't a bad person for dealing with this, but I wish our culture would stop trying to pretend problems aren't problems.
