@Zonder it was started by CurlewKate, asking if anyone had any news about the superinjunction, covering stories that Keir Starmer is gay and/or has fathered a love child with another woman.
The point being to prove that a) there is no superinjunction and b) it's all ridiculous, conspiracy nonsense
Cue many/most posters completely missing the sarcasm of the OP, and the fact that clearly these were fabricated stories, but also going on to discuss how dreadful KS is, both being gay and keeping it a secret, and having a child with a woman who isn't his wife, bearing in mind that he talks so much about integrity.
Lots of homophobia and even more vile speculation about KS.
