"Are you a heretic?" is not making it personal. "You are a heretic." is making it personal.
Of course there are exceptions and I have little tolerance for posters finessing the guidelines trying to get in a personal attack by ending it with a question mark, e.g. "Have you lost your mind?"
The copyright issues have been resolved and the air has been cleared. I doubt if it will happen again.
So it's time to put that issue to bed and return to the issues of the thread. Otherwise, it would making the thread "about" another poster which is also a form of "making it personal."
Discuss the issues all you want, but do not make it personal.
