I see communication as an exercise in reciprocity. E.g If I listen supportively (and, usually, enthusiastically!) to you tell me about Johnny's hockey hat trick, then I expect you to listen to me tell you about my son. I'm usually quite effusive about other people's children's accomplishments, and I find this attitude is beautifully contagious.
That being said, I have no problem pointing out when that reciprocity is breached by the (very) occasional bad apple. This may not make me friends, but I don't really care. It's my job to be a loving, supportive parent, not Johnny's mom's "BFF". Maybe I'm more blunt than the average forum member, but I don't feel it's my responsibility to manage someone's inferiority complex if I'm making a disclosure that a reasonable person would find acceptable, even interesting
ETA: I realize that I may temper this position if my son ultimately attends PS, lest he become a pariah because of his zealot mother.
