Criticism of an ideology isn't any kind of a phobia or "ism", no matter how much you stomp your feet, slam your eyes shut, and try to wish it so. Criticising peoples ideas and choices is the most valid form criticism there is. And that's what religion is - a chosen ideology that helps people make choices based on the ideas and tenets of their chosen faith. Yup, it's a choice. It's not something biological, and it's not something that can't be changed. Why shouldn't it be open to mockery, criticism, or questioning?
