Actually I would say that the #MeToo movement, the prosecution of Weinstein and Epstein were the trigger points for the culture wars (though Trump’s ‘grab ‘em by the pussy’ tapes were mixed in with that)… ie there was a global cultural awakening to the fact that (often young) women (together with young gay men) were victims of predatory wealthy, largely white, men and that we had been deceiving ourselves for a couple of decades that women were safe and regarded as equals.
THIS was the pivotal point for me - and for many pubescent girls such as my 12yo daughter who’s periods began the summer of 2016 against this backdrop. Her very logical, Aspie/ADHD brain deduced it was better to be a boy than grow up in a world that is hostile towards women and which has fuck all real interest in protecting women and girls. I couldn’t come up with a convincing riposte as, after all, this is the world we were seeing in the media, on the news and is a position that governments/political parties have since doubled-down on (the SNP, the Democrats, the Greens/Labour/Liberals here in the UK).
They did not act quickly enough to protect women’s sports, to redefine ‘woman’ as biological female for legislative purposes, they did not step in to ensure that policy in the NHS, schools, CAMHS was science and research informed rather than ideologically shaped by unelected individuals/organisations who should never have had access to the ears of policy makers. The president of the US from 2016-2020 has eff all to do with what has been happening here in the UK and Europe.
I think it is lazy and, frankly, bloody stupid to blame this on Trump or his party.
