This is very sinister - you can always spot an MRA in disguise by their aggressive tactics - mob complaining to Google (the boss) is a huge escalation - as Google has the power to block MN. That would severely disrupt their business income and operation.
I agree. We shouldn't scoff at this. This is dangerous. This scares me. They are determined to stop women from talking and so far they have been largely successful at it. Mumsnet is one of the few places in the world where women can freely discuss the logic and the impact of trans ideology. Almost all other feminist/progressive sites run complete censorship on this issue.
Tech companies increasingly control the world, and trans-identified males are hugely overrepresented in IT. It only takes one influential TIM at Google to completely shut down women's free speech. And they need to shut it down, because open discussion exposes this anti-woman, anti-child, anti-reality ideology for what it is: the new patriarchal state-enforced religion.
