I know you aren't trying to make JC feel bad, and I understand how impassioned Rottie owners feel about their breed. They get such a bad rap anyway.
I am not sure how I feel on the subject, I wonder if Arthur was blamed b/c he was the bigger dog and Charlie was the smaller of the 2 and unable to defend himself as well as a big dog would.
My heart breaks for JC and Bella - I wouldn't want to be in their shoes.
I have never had an agressive dog, so that I can't walk in their shoes. I do try to see both sides, but I really don't know how they feel.
{{hugs to all}}
