And whats wrong with accepting these people who are careful? Some are vegetarian, some like kosher and others pick and choose even different food items based on whatever they think is right.
People spend extra time, effort or money to feed their pets whatever food their pet like. But when it comes to other human being we run after them calling them show off pious people. We get annoyed and become judgemental?
Please consider that your right may be someone elses's left when it comes to interpretation of religion and beliefs.
I am not against anyone's right to eat the best out tehre. What i am against is the holier-than-thou attitude and doubting other muslims.
