The liberal female teachers that give up staying home to raise their own children in order to pursue a teaching career can't overcome their natural internal instincts to be a mother, and end up thinking they have a right to raise other women's children behind those women's backs, often in immoral ways the kids' parents don't agree with.
Once you see teaching through that lens, you can't unsee it. Female teachers everywhere trying to raise other people's children instead of only sticking to teaching the subject at hand.
