What would they refuse Communion for?
Reading Michael Rose books? Listening to Rush Limbaugh? Telling Teddy Kennedy jokes?
How about the offense of petitioning for the Tridentine Latin Mass? Kneeling to receive Communion? Hmm, we're getting warm. Kneeling after the Agnus Dei? Well, now...
How about the offense of homeschooling your innocent little children instead of sending them to a parochial school that has diocesan-mandated offensive sex education? Actually, that has already happened in some places, hasn't it -- refusing First Communion to the innocent children of conscientious Catholic parents.
Our Lady, Mother of the Eucharist, pray for us and our Church! Amen.
