[Harry Potter] - Can I disenroll my kid from Hogwarts?

I'm a muggle with a muggle husband, and our middle son received a letter from Hogwarts. It appeared to be a good deal so we enrolled him in. But we are appalled with the low level of education my kid is receiving. 3 years in and his reading level and math skills are way behind his little sister. But it was ok, they have different objectives, magic is hard and we can always enroll him in summer school for remedial classes, but the worst is his behaviour.

He has become really hostile to us and his siblings. He thinks we are inferior for not being able to use magic. The kids at school have been calling him "mudblood" what appears to be a racist slur, even some teachers engage in such behaviour. Headmaster Dumbledore haven't been really useful in this. We think regular education would be better. Would he or us face any backslash?

Every year except 1997, when Voldemort was in power, attendance to Hogwarts is optional. However, that only really applies for wizards.

As a muggle, you have  very little to no legal tools  to try and get your kid out of hogwarts. There's a very high possibility that the ministry may bypass your authority and assign a guardian to your kid that will either send him to hogwarts or homeschool him till he  reaches the majority of age 17.

Sadly, the alternative is much worse, because an uneducated, untrained wizard forced to  live a muggle life would 100% turn into an obscurial, which would be bad for your family, the wizarding world, and your entire neighborhood.
