Sadly, MNHQ are OK with the thread being derailed. I give up. This is the email I recieved:
While we absolutely understand that this is a sensitive and emotive issue, particularly for posters affected by disability and the current rhetoric around benefits, the thread sits in Site stuff, which isn't a designated support area. It's intended for users to raise concerns with us and, as such, tends to attract a broad range of perspectives. It's also worth noting that while some areas of the site are less suited to in-depth ideological debate, there’s no board on Mumsnet where respectful disagreement is automatically out of bounds.
The post you've highlighted appears to be sharing factual information, and while we appreciate it may come across as provocative or upsetting in the current context, it doesn’t breach our Talk guidelines. We’d typically step in if a poster were being personally abusive, engaging in hate speech, or persistently derailing a thread that is clearly intended to be supportive. In this case, the thread has developed into a wider debate and includes a variety of strongly held views from multiple sides.
I assume the Talk rule about no deliberately inflammatory behaviour no longer applies.
I suspect this post might be deleted. I might even be banned.
