I don't think people usually intend to hurt, although if you hang around you will see that there are posters who are much more black and white in their thinking than others.
Sometimes people are responding to hurt they have felt themselves, so to use your thread as an example, someone (like me) who found breastfeeding impossible will perhaps take less kindly to hearing about a husband telling his mum that not persevering with it is 'lazy' than would someone who felt that a grandparent had a right to be involved in the way her grandchildren are brought up. You are going to find people with a much wider range of experiences and backgrounds on somewhere like this than you will elsewhere, which is what makes it valuable, and also what can make it difficult.
As others have said, only hearing voices that agree with you (which is not synonymous with 'supportive', incidentally) isn't particularly helpful - you could have told yourself everything they have said. Listening to alternative points of view can be difficult, but is actually more supportive, as if you genuinely listen to them and consider whether there is any truth in the perspectives you can gain a rounder opinion yourself. Obviously you don't have to agree with anyone, or act on any suggestions - that is up to you - but writing people off simply for having a different point of view is pointless. Why bother asking if you are only going to listen to those who agree? Also, suggesting that you will leave unless you get 'support' won't get you very far either. The 'flounce' is not highly regarded on any internet forum. It is insulting to those who have taken the time to make suggestions about your dilemma, whether you agree with them or not.
