I did Home ec in the '80s. and the girls did wood work and metal work too.There are several political movements grabbing the limelight in the UK at the moment. In no particular order, BLM, the LBTQ+ gender-nazis, and the feminists*.
The last-mentioned are relevant, here.
Having the girls doing cookery and the boys doing (now, arguably defunct) metal- and woodwork was deemed to be reinforcing gender stereotypes** and keeping women in the home/bound into poverty/unable to self-determine. This is, or was, deemed to be Very Bad.
One could also take the view of course that despite the propaganda, most people are heterosexual and will eventually end up in heterosexual relationships. Having around 50 per cent of those in those relationships able to put together halfway decent meals is probably a good thing. That doesn't mean that the women should have to do all the cooking (although don't tell SWMBO that).
*One could also describe them as Marxists, Marxists and Marxists.
**Increasingly difficult to equate as, according to the Alphabet Spaghetti lot, gender is a political construct and doesn't really exist. We will reach a point of being unmanageable as a society if all this lot get their way.
