Much in the same way that many people are not allergic to milk, but have lactose-intolerance, and we don't smugly ask "do you have a milk allergy" if they order substitutions, and then dismiss them as stupidly following a trend if they don't SPECIFICALLY have a milk allergy. • When people notice they have digestive issues common of lactose-intolerance, we don't judge them for self-diagnosing a lactose issue, but if someone experiences a similar situation with wheat, we stand ready to mock them, behind their back or otherwise.
