I tried to post a comment on the article, but couldn't. So I'll "preach to the choir" here.
These same people who call his visit "inappropriate" and "insensitive" would probably welcome with open arms the parents of the killer, as well they should. They were victims of the horrible tragedy, just as were every American who gasped when we saw it on CNN. But these people think the law-abiding businessman, who made a legal transaction as part of his legal business, is somehow to blame for the events of that terrible day. That's like blaming the person who sold the 9/11 hijackers their tickets. If they are looking for someone to blame, all they have to do is visit the cemetery, and look for Seung-Hui Cho. It was his fault. Nobody and nothing else, not even the guy who sold him the gun, can be blamed for killing 32 innocent people that day.
Rant complete. Thank you.
