Sonnar Brian, firstly let me say I'm a great fan of your posts here on RFF, with all your valuable expertise and advice on things optical, but I did see the one post referring to Charlie Kirk. Perhaps I missed others before your redaction, but the one I read seemed acceptable to me in context.
I agree that you were right to edit that particular phrase but to lock the thread is an overreaction.
On the other hand I recognise "NY Journal" contains almost nothing related to RFF's normal business and Calzone has been wholesale indulged by letting him blog shamelessly for several hundred pages, but that thread is a leavening diversion and useful public information for a whole lot of life matters. Calzone is a character that should be nurtured in any forum, no matter how off-topic. He is a long-standing member.
As has been mentioned above, there have been a number of very bright contributors who have been turned away by unfriendly ad hominem backchat, who have not been adequately protected or backed by other members, and I regret that very much. It would be a shame to lose another.
