You may find it weird, and so may others. I won’t disagree that it seems a little weird. However... I think it took a lot of courage for them to do that. It must have been extremely painful but it shows me how much they valued the life of their son that passed away. It’s none of your business or anyone elses how they handled the death of their son. They did what they thought was right for them and their other children.
I agree with most of that, except this.
Nobody, I mean NOBODY would have know about this if Rick Santorum had not, himself, told the media about it.
Anyone can assign a value to it as he is a POTUS candidate now. They can decide if it's important or not, and whether it affects their vote.
RICK SANTORUM BROUGHT THIS INTO THE PUBLIC SQUARE.
