let me just say in my defense this is a pet peeve thread ... meaning my peeves dont necessarily need justification and also i understand if the reason is when people dont react well when they eat gluten and that is why they choose not to indulge ( i had to stop eating raw jalapenos as it became uncomfortable for my tummy) and i dont fault them for that
my peeve is with people who are doing it because its the new "fad" diet and as bagochina stated " the holier than thou attittude" that often goes along with it
i am sorry for being unclear... and also my poor grammer
I wasn't directing my (now that i re-read it, slightly over the top

) tirade at you, unless it was simply a case of your post being closest to mine, if so, carry on.

My peeve is people who seem to have this overarching denial that such allergies exist. I do understand that for people who have true allergies to gluten (i actually know 2 people who have serious allergies - one woman can't use the toasted sandwich maker at work in case someone has used normal bread in it

) it might grind their gears a little to hear people who simply avoid gluten due to some idea that it means they'll lose weight or something, but attributing it to being gluten intolerant. For people with true allergies to these things, life can really suck at times and eating well can become a really expensive venture, especially if they DO want to have bread or milk in their lives.
I've also seen the new trend of going sugar free bring about an advent of people who have read "Sweet Poison" and have taken a fanatical view on going sugar-free - a girl at my work spent a good couple of minutes berating me for eating a peach about 3 months ago, because I was 'poisoning myself with fructose'. I just nodded and smiled, whilst enjoying the juice of the peach running down my chin
Anyway, a pet peeve of mine is thoughtless people - a friend recently told me about speaking with a friend of hers about having trouble trying to conceive a child, and the friend banged on for about 10 minutes about how fertile she was, and how 'she only had to look at her husband to fall pregnant'. Said friend said something to her about how it may not be entirely appropriate to say such things to someone who had just finished talking about how much trouble they were having trying to conceive. This can apply to many situations, but people just seriously need to ensure that their brains are in gear before engaging their mouths...
