If you can equate a parent watching as her child is killed by someone with Andy getting booed, then I honestly don't know what to say, except I'm assuming you are not a parent.
I thought it was obvious that EJ wasn't making a comparison between the two. The point being made was that it is sometimes harder to excuse someone doing harm or insulting someone we care about than it is if someone insults or harms us.
I'll make that clearer. When I was at school I had a friend whose mother died from cancer. My friend never really recovered from the loss of her mother and it happened before she was a teenager. Now, I knew another girl who relentlessly teased my friend for grieving. Had this girl had a go at me about something I could have let it go pretty easily, but she didn't, she had a go at my friend, so I made damned sure she understood what a pathetic, nasty, vindictive little cow she was.
