Exactly! I do NOT like Biden whatsoever. But, if I was a teacher, I would NEVER discuss politics with the children and tell them which way they should be leaning and who to hate.
Not that I liked Trump either, but unfortunately A LOT of teachers were doing that to kids as well.
This led to many enrolling their children in private, Christian schools where they felt politics would not be included in the curriculum. It's ironic to see it happening still, except from the other side this time.
In a nutshell, nobody should be teaching children to HATE certain people for political reasons. Let them be kids!
