The Pope has every right to prevent God's children from harming themselves through dis-respecting the Presence of the Lord through dis-belief.
Blair didn't choose to receive the sacrement because he wanted a snack- he believes in Jesus, why does that make him unworthy?
Blair hasn't "chosen to receive" any sacraments that I am aware of. Nobody is worthy, it is a question of whether one affirms the faith or not. Not the watered down version, but the entire faith.

I am a Protestant. My wife is Catholic. We had planned to take our daughter to her first Easter mass this weekend. If I can't participate, I am not going to sanction such a divisive and exclusionary practice by going to get my "blessing." The requirement of belief in transsubstantiation is man-made law, and the Church does itself a disservice by turning away believers based upon it.
