Thanks for writing, lib, and I'm sorry to hear school is off to a rough start with your little one!
There is really only one solution here: home school. The unfortunate reality is that in today's society you cannot completely protect your children from other people's "world views." It sounds like you have been doing a great job up until this point if you legitimately need advice on how to talk to a teacher after 8+ years of schooling, but it is simply inevitable that some degenerate will sneak into those school walls eventually (the slutty teacher in this case).
If you truly want to keep owning the libs and their anti-white agenda, you need to retreat to a safe space ASAP.
