Nevertheless, I will call a wafer/cracker what it is, and remind you that while your faith may believe that it is magically transformed into the body of Christ, most of us on this planet see it as just a flour-based food product, nothing more, nothing less. I respect your right to believe in what you believe, but don't think I have any obligation to genuflect towards Rome, Mecca, or Jerusalem.
You have no obligation to perform any religious observation that you do not believe in, and you are smart to avoid offending others.
I agree 100%.
Do you hold any religious beliefs, if I may ask?
Straw man. No one's asking you to genuflect to anything. I've no interest in your assent to Catholic teaching on the Eucharist. The issue at hand is not whether or not the Eucharist is what Catholics say that it is. The issue is the intentional public desecration of that which others hold to be sacred. Stripped away from any debate about the merits of religious beliefs, what Myer's has done here is a gross violation of simple common civility in the public arena. And that, to answer your initial question is why this issue should matter to "rational human beings" like yourself.
