I didn't for one minute think it was aimed at me POGS, nor was any of what I said aimed at anyone in either of my posts. I was really trying to make the point that one person's opinion can be someone else's judgement.
I think people do get upset on forums from time to time. When we first moved to France we had a problem over health cover, because of a change of government rules and the unkindness and unhelpfulness of some posters reduced me to tears many times; other people were amazingly supportive and in the end a group of people got together to (successfully) get the rules changed for existing residents. That was the worst and the best of on-line forums.
Sometimes the aggression is deliberate, sometimes it is unintentional because people write in a certain way and other people read too much into it. I think if I feel uncomfortable now then I just back off for a bit, don't read it and don't post. I certainly don't expect to find friends (or enemies for that matter) on forums, just enter into a good debate. If I don't agree with someone's views then I say so, but I try my best never to personalise it and never to post anything unpleasant about another person however much I disagree with them.
Hope this helps without sounding sanctimonious!
