Nanwind Implicit in your post is an assumption that if someone asks for help or advice we should support them, regardless of whether supporting them is the right thing. Some people's problems arise from their unreasonable behaviour and is it right or fair we should support them and say how we agree with their stance.
For example:Someone posts to say that they live a 10 minute walk from a new GC and want to see them every day, but their DS, says, no, once a week, because everyone wants to see DC and he and his wife want some family time alone with their DC. Would you immediately agree with this person, even though their demand is clearly unreasonable? Isn't kinder and fairer to point out that it is her DGC's parents to decide on visits, not hers to demand?
Sometimes the person seeking help gives too little information or we suspect we are not getting the whole story. It is not reasonable to expect us to give unreasoned support for every problem posed.
Oh dear, does this make me, one of the critical and insulting posters?
