You are assuming sanity
I am with you there, I do not understand why individuals who go out of their way to make public statements on blogs, fora, twitter and other places don't understand that people will disagree with them and make public replies. If you can't handle criticism and disagreement, you should not make public statements.
They seem to equate disagreement and criticism with personal attacks. While some criticism can be personal attacks, not all are.
They seem to think that all of the internet should be their own personal safe space. This makes me sort of understand the drive behind the safe space push at A+. They want their own corner of the internet where they can have their own personal safe space but still put things out there for others to see.
Frankly I think they all need to just grow up
