OP, you made me think. It’s been bothering me for a while. I suggest a new rule: No direct discussion between genders. Say “Prince” and “Princess” (fictitious screen names) start a conversation within a thread, addressing each other by their screen names or joking around. That would be akin to pen-palling. The mods would have to stop it.
That wouldn’t solve the problem, though, of a married poster thinking, why can’t my wife be smart and good-natured like eclipse? Or, why doesn’t my husband have Poppa’s sense of humor? (Of course we can never know how posters act IRL, but it’s human nature to form impressions and draw conclusions.)
Bottom line, we should limit CR to informative and serious discussion to help each other, not to impress each other, especially those who happen to be of the opposite gender. Joking and chattering should be allowed only in male-only or female-only threads.
