I find it really sad that some people live their life with restrictions just based on a fear of what others think.
It's not that surprising, is it, though? Mumsnet is full of small-minded and viciously judgemental posts on the average Tuesday.
I'm very appreciative of the kindness and good advice on Mn, as well as the company it provides for large numbers of clearly very lonely/socially isolated women who use it, but I think that one of its most negative sides is that it demonstrates to anxious or self-conscious people that yes, some people are judging you -- your clothes, your house, your housekeeping, your BMI, your accent, your lawn, your relationship or lack of one, yyour children's public behaviour, diet, and educational achievement, or the fact that you don etc etc.
It gives an actual voice to the inner critic these people, usually women, suffer from to an unusual degree.
I have a friend who, despite being ridiculously successful in virtually every area of her life, says she avoids Mn despite having had excellent pregnancy advice on it previously, because it makes her anxious about being judged.
