Hi Leep,
I stay well clear of these conversations now as I've had my fair share in the past. In fact the 'negativity' of posts was far far worse a year or so ago. You have to be able to accept that you will get some hostility from some people, you ignore the hostility as best you can and concentrate on the posts that have offered suggestions to you original post as this is all you are interested in isn't it. That way you get a lot of really useful information from this site.
It's rude to mention names, but there is one in this thread who 'you' may feel is being hostile or perhaps unhelpful, but if you can look past that you'll find a lot of very useful information from this member as his knowledge is great. It's not easy as sometimes
you may want to tell him he's being a bit of a knob but you can't because he's actually right 97% of the time so you just sit and smile and say thankyou for the useful information
