A few things....
Funding for artists has seriously dried up over the last decades or so.
At the same time places like the arts council and many sources of charitable funding they can access have been well and truly EDI'ed. particularly around lgbtq etc.
The Arts Council is extremely trans positive.
There is a lot of funding for arts charities / groups / galleries/ museums who focus on minority groups, diversity and educational opportunities. (Do you see how it works?!)
Coupled with active grassroots deplatforming of any artists who speak out about this (see the knitting world, pottery world, circus world, dance world - Rosie Kay etc) there's a perfect storm for the flourishing of queer stuff for kids.
Also.
The Arts Council's Artsmark award (for schools) will now be delivered and coordinated via Goldsmiths. Well known for having many lecturers who are v pro trans ideology.
Why does this matter?
One of the points of and Artsmark for schools and the Arts Award for children is to actively encourage involvement with local arts organisations such as galleries, museums, theatre groups, art groups etc. They all rely on educational delivery for funding. Public museums and galleries especially so. They can be centres to deliver arts awards for schools (the awards cost) and bases to deliver training to teachers and others for Artsmark, though there's usually "bridge" organisations set up for this.
It's all very tied up.
