Why would you want it to be bitchy for?
Bitchy comments can be abusive, offensive, upsetting, a form of bullying - the very things that people post in the relationship boards about? We wouldn't tolerate if it was our own son/daughter/family member being bitched about?
Now you may think you are being funny, outrageous, outspoken, opinionated - but you have absolutely no idea who you are speaking to here. There are people who post who have PND, mental health issues, are generally feeling down, at their wits end and those people need support not back biting.
Maybe it's worthwhile remembering that we are all human beings that deserve respect, and that we are all someone's son/daughter/sister/brother/mother/father. Just because most of us post with online aliases doesn't give us the right to post whatever we like and everyone else. There should be consequences to bad behaviour, trolling, baiting, people being hurtful and offensive.
So if we are moving away from the bitchiness towards a more supportive forum, then good. What's wrong with that? Forums don't have to be a 'baiting' ground where you can defame and and upset people or take your bad day out on someone else.
