This is slowly chipping away at parental rights.  Some of this should be left up to the parents to teach, and especially not taught to young children.  From some of the curriculum I have seen that is in the name of SEL, it will only create more division, and will cause more anxiety.  There is a bigger agenda here than what is being "sold" to the public.  We may need changes in education, but we do not need brainwashing!
