Remember, all you’re getting is one person’s biased account of what happened. There actually is no hard evidence that she tried to politicize the funeral.
I doubt a card was offered to anyone who was in the act of receiving communion. It may have happened afterwards, or before hand while people were lined up. A person unfamiliar with the ceremony might not realize it’s not polite to talk. It involves a degree of sitting and waiting as the line shuffles by the priest.
I don’t think that a funeral is an appropriate platform for political activism, although, as many have pointed out, it’s unclear that Ms. Knoll actually engaged in any political discussion at the funeral. I just wanted to make a brief note:
The Pittsburgh Tribune-Review is hardly a liberal newspaper; it’s owned by Richard Mellon Scaife, a long-time conservative activist (and leader of Hillary Clinton’s “vast right-wing conspiracy”), and is pretty well known for its conservative editorial content.
