I suspect I'm going to regret this. If someone posts something in a "I need to let off a random bit of steam" kind of way (as opposed to a "I think x would you like to debate it with me" kind of way) and you disagree with the cause of their need to vent, do you
a) tell her she's wrong wrong wrong even when several other people have already expressed the same view
b) gently point out she could look at it differently, your purpose being that seeing it differently might help her or
c) just don't post.
sorry but I personally go for b or c and I think whatsername on the clothing thread got a bit of a hard time
