Other than homeschooling? Make sure to be a positive influence and someone they can rely to and trust. If they feel happy in your presence and can talk to you about things that bother them or seek advice about life, they won't need to turn to faggot teacher's for guidance. Also if there is good communication between you and your kids, you will be better informed about what's going on in school. Teach them to think for themselves and not submit to peer pressure. Teach them that they are individuals and not just a member of some group that was forced upon them.
