The problem is Wigsie, that the people who may find the thread objectionable, may not even post on it or this.
Who defines a defensible thread is a good question. Ultimately it's the membership of the forum and increasingly threads such as Yenners Cheryl Cole thread have attracted a fairly unseemly response. I know you've noticed that because we're having this debate, I just feel you're seeing it from the wrong angle.
Instead of having a bash at the P&L crowd, ask yourself why they are posting more into these type of threads, ask yourself why more and more people are objecting to these type of threads and why they end up in 101.
Far from it being some kind of leftwing conspiracy, I think you'll find that more and more people are losing patience with posts like that. I've read comments from women, those who've left them, that the forum is a bit too testosterone fuelled for their liking.
I'm pretty sure that Shaun wants an inclusive forum, so it's up to us, as members, to think a bit more about what we post. That doesn't mean that we shouldn't post threads about Cheryl Cole but there's more than one way to make the post. There's the 'I hate Cheryl ugly Cole' route and 'Why is Cheryl Cole popular' route, the same but different. I don't think anyone's arguing for a suppresion of subjects, merely a different way of expressing and discussing them.
