What Twid said. I also don't think there's a problem with having preferences or not liking something because of texture or similar.
Of course you don't, cracker. 
Don't you deal with that sort of thing for a living?
Not anymore! Now my menu consists of two choices: take it or leave it.
And before, when I was subjected to the indignities of running a restaurant kitchen, most of the front of the house staff new better than to come to me with requests based on pickiness as my usual response would be something along the lines of "well if they can't find anything on the fucking menu that they fucking like, maybe they should go the fuck somewhere else!"
This does not apply to actual allergies, I have all of the sensitivity in the world about that and will go way out of my way to be accommodating. But when someone wants this dish but without this or that component because they really just don't like those? Well fuck the fuck you, cocksmoker, either find a dish that your picky ass DOES like or go to fucking Wendy's.
BLESS YOU, SIR.
My best friend is deathly allergic to certain tree nuts, and all bivalves. She once went into anaphylactic shock at work because the "peanuts" sprinkled on the Thai noodles in the cafeteria were actually chopped mixed nuts. Her face and tongue swelled up after kissing her boyfriend, who had hours before had a cookie that had walnuts in it. It's very, very important that she not be exposed to tree nuts. Luckily, she can, and will, eat just about anything else that comes her way, and is damn fucking grateful for it.
I have another friend who is a Celiac, and can't have any wheat at all or his insides will start eating themselves.
Then there is the LEGIONS of friends who have recently jumped on the gluten-free and food allergy bandwagon because they found an itchy spot or they feel sluggish after too much pasta, who give themselves permission to "cheat" if they want something badly enough, but otherwise make a huge deal about all the things they "can't" eat.
Oh, so I have to make gravy with rice flour, so that you can save your daily gluten allotment for a cookie? Fuck you!
These people really chap my hide. Because they give the world at large the impression that someone who is seriously allergic ("cheating" at all would make either of my aforementioned friends seriously ill, if not dead) can still just have a little as long as they don't notice it. Just a LITTLE pecan flour on the chicken won't hurt, right?
I have another friend who is, sorrow of sorrows, allergic to onions. Needless to say, people assume that she just doesn't like them, but she really just can't have them at all because they make her very unpleasantly sick. She solves this problem, mostly, by not eating anywhere but at home, and has never once made an issue about it.
The people who don't like this and that, and who have rules about what's "gross" and what should "never be done" because they think a food is disgusting, make me want to go into a whirlwind slap-fest. It's one thing if they apply their picky picky princess standards to themselves, but the ones who go about judging and ewwwwing at what other people eat truly make me want to punch a bitch in the face. It's not, actually, cute to be a brat.
