It wasn't my comment, but here's just one I found with a quick Google search:
The Washington Post reported that a kindergarten teacher in Massachusetts said that he exposes children to the terms transgender and gender queer, though he does not provide complete definitions since that would be too much for kids in kindergarten.

There's were a ton of other hits over the last 7 years though that some educators want to start basic sex ed as early as Kindergarten. Not necessarily all the nitty gritty of it, but they want to introduce sexual preferences or gender related terms like gender fluid. They also discuss anatomy.
Those early years are important for young students, they should be focusing on more important things imo like reading, math, tech, etc. My son spent his entire Kindergarten year on lockdown because of the pandemic. The only classroom instruction he got each day was an hour of Zoom meetings and the parents were expected to do the rest between 5pm quitting time and dinner. Needless to say he was behind when we ultimately moved and switched schools.
Parents in California have already complained about this sort of thing and fought back. They don't need this kind of stuff in the curriculum this early. Our country is already behind many others when it comes to child education. I don't see this kind of program helping to alleviate that.
