According to their website, Girls Who Code runs a set of clubs: https://girlswhocode.com/programs/clubs-program
The books are not the club, but the two seem closely linked.
Regarding your son, I don't agree with not allowing boys to participate. (Which I doubt by the way) BUT I do understand why this could happen.
Regardless. The situation with your son doesn't add anything to the discussion about the book being banned

That's undoubtedly encouraging news to Moms for Liberty. If it was like that everywhere, they might reverse their stance.
One anecdote to another, as a man, I have participated in numerous "women in engineering" tech days and sessions. I don't find them unwelcoming at all.
Then they must ban football, baseball, basketball, tennis, soccer, etc
> There is no Boys Who Code club at our school or any other.
Why do you think that is?
