That all sounds very wise and inarguable. At first.
After awhile, I pondered assorted threads that were unrelated to Mystery Shopping. We have talked about pets, clowns, hurricanes, Olympics, and AD/OD (Alzheimer's Disease and Other Dementias). Briefly, we discussed bgriff' in a manbun and wondered if he would like to have his eyebrows threaded. We did not find out everything we wanted to know about those concepts. Baseball and gardening are annual and perennial favorites. We can laugh at ourselves and get a few pats on the back, if we want them. We are watching a kitchen become a new version of itself. We are watching a cat become re-aligned with his person. We told a few jokes, had a few laughs, and generally made at least a quasi-human connection.
All of these ideas reflect values.
Politics and religion reflect values.
At what point would the values banning stop? Once you begin to limit topics, you might not be able to stop. Soon, the entire "General Chat" section could disappear. If you want that to happen, by all means begin to limit topics. If you believe that board does not belong here, you must take any actions necessary to ban it.
So, how do we value assorted topics? What do others think? Would we be able to stop the banning before entire portions of the forum as we know it disappear? Would we notice or care? What do we think?
