That is not nice
FWIW Arthur's a Catholic priest, and while it's true that he and I disagree often (incl. over his position taken on this thread), he has my respect.
The tone of the article got my goat. It seemed like an ever-growing set of demands. Where are all these special instructors and minders and mentors and facilitators supposed to come from? Oh, yeah. From the limitless funds and time and people and resources of the church.
The fact is that there are some places and events and activities that are not for absolutely everyone. Some children cannot and should not attend church because they cannot control their crying or screaming. They can be brought to church when they are older and have learned enough self-control. The very fact that a child—autistic or not—cries and screams in church is a clear sign that he does not know where he is or what is going on around him.
