Nope. It's not cherrypicked. It's a growing phenomenon which is seen in mass-market and which schools have been embracing. See what is happening with this curriculum in Canada:
"the Sogi curriculum
started in British Columbia in 2016 and
is quickly spreading throughout Canada"
On the Sogi site it clams to be present in some capacity in 60 of 60 school districts in Canada
https://www.sogieducation.org/resultsCanada has 60 school districts -
https://en.wikipedia.org/wiki/List_of_school_districts_in_British_Columbia - "This is a list of school districts in British Columbia. British Columbia in Canada is divided into
60 school districts which administer publicly funded education until the end of grade 12 in local areas or, in the case of francophone education, across the province."
The Sogi site in the above link claims to have 2500+ "Sogi leads", presumably administrators or educators in various schools in Canada who have embraced the curriculum.
With this kind of network there are clearly tens of thousands of children in Canada being affected by this one LGBT organization alone.
Canada has about
10,100 elementary schools, for comparison.
Back to the video, it demonstrates that they are using teaching aids such as the 10,000 Dresses children book:
https://www.amazon.com/10-000-Dresses-Marcus-Ewert/dp/1583228500Book description: "Every night, Bailey dreams about magical dresses: dresses made of crystals and rainbows, dresses made of flowers, dresses made of windows. . . . Unfortunately, when Bailey's awake, no one wants to hear about these beautiful dreams. Quite the contrary. "You're a BOY!" Mother and Father tell Bailey. "You shouldn't be thinking about dresses at all." Then Bailey meets Laurel, an older girl who is touched and inspired by Bailey's imagination and courage. In friendship, the two of them begin making dresses together. And Bailey's dreams come true!"
The boy's dreams came true! This is clearly a propaganda book to paint crossdressing in a positive light, taught in a Canadian classroom in a curriculum which is described in the video and on the organization's website itself to have spread all throughout Canada in growing popularity. Many other schools or districts decide on their own to stock these types of books without joining an organized network like this.
The video goes on to describe that children complain about being confused about their gender.
