Robin's house, Robin's rules. If a guest to my house - even one as familiar - were to start up with another guest of my house - even in a side room - I think I'd have words as well. I probably would not have had words out in the open, but there would be words.
One of the things I love about this site above most I've seen for most any genre is the civility and lack of drama and trolls. Understandably this issue has high visibility largely because of the parties involved. However, it only has high visibility because it was made visible.
Frankly, the biggest shame would be any lost content.
IMHO, there's nothing to see here. Lets move along and play some pin
Just my opinion. YMMV
