As the OP from the thread you mentioned, I agree.
That person who chose (and chooses again and again) to post as Anonymous Coward (if the shoe fits, wear it) could have driven the conversation completely off-topic.
Fortunately those who had something useful to contribute to the discussion managed to do so, and I learned about something I was previously unaware of (Mouse::XS).
Perhaps instead of using PerlMonks for personal therapy, these downtrodden, socially-inept folks could go to a qualified therapist? Or we could simply not post things that we wouldn't CC our mothers on?
