These latest pronouncements suggest, however, that their support for gender ideology is not driven by expediency at all. The more frightening truth seems to be that they actually believe it.
One element of this is that an absurdly large proportion of last year's intake of Labour MPs is gay. I've heard an estimate of 25%. Partly this is Lord Alli's influence on candidate selection, but that doesn't explain similar trends in the Lib Dems and SNP.
I should state, I have zero problem with gay MPs. I don't even have a problem with gay people being a bit overrepresented in Parliament. It might be a problem if they're massively overrepresented and they've overwhelmingly been indoctrinated by Stonewall. Chris Rock's comedy routines used to distinguish between black folks and n***s; maybe we might distinguish between gay people and alphabet people.
A second element is that quite a few senior Labour MPs have trans identified children. I don't want to quantify this, because families have a right to privacy and Labour gossip might not be accurate, but that could include anything between three and six members of Starmer's cabinet. We know the chill factor that can come with having just one trans parent in a workplace.
Finally, I think a lot of our political class are highly educated but just not that bright.
Put those things together, and it's a bit like having 100 Jolyon Maughams in the Parliamentary Labour Party.
