I honestly do not see what the big problem is! There is no argument amongst members going on here, it's just a discussion like any other, a little heated perhaps but no worse than when we complain/discuss about politicians/doctors/nurses or next door neighbour. AND same as in any discussion/argument it's the individual persons choice if he/she wants to read it or take part in it, those who don't will, as has been mentioned here, ignore it.
I don't see the difference in discussing a certain person or persons than discussing anyone else whom we'd like to complain about (ie: NHS, Politcians, HCP or whatever), as long as it stays a discussion and does not turn into a big argument amongst the forum members I don't see any harm in.
