As to the comments that anyone that disagrees with the 'clique' is attacked, I don't buy that. what I see is a handful of posters that continually post offensive, judgmental stuff... people attempt to challenge their thinking... then they get angry and say people are bullying them.
If someone said IRL what some people say about smoking mums, single mums etc etc I firmly believe people would say hang on, that's pretty nasty, have you considered a b or c in the equation? which is what happens here. It only descends into back biting when the member saying outrageous things then loses the plot and says they are being picked on.
Own you words. If you are strong enough to say what you know is going to cause friction, expect there to be backlash. Otherwise it does come off trollish.
