Because they're teenagers and not men.
Teachers are all liberal women, and liberal women are taught to hate, fear and loathe men.
In fact, they get harassed by their "group peers" for dating a man - the purpose of dating men is to pick them apart and dump them, while hating them some more.
Why? Because Leftist women are the new men. Leftist women claim male attributes for themselves while passing laws to jail boys and men for being masculine.
It's a control technique, used by Leftist women against liberal women.
But like all Leftist/communist crap, it's fake. It runs solely on force - intimidation and destruction of those who don't go along.
So young female liberal teachers are looking at older teenagers and, as liberals do, figure they've found a way out of their dilemma. Teenagers aren't men, and they're not boys, so they can satisfy the women's desire for a "male" while fulfilling the feminist requirement that they totally dominate the relationship and keep it as unequal as possible.
And it also fulfils the cynical feminist position that the only thing a "male" wants is sex, and will do anything for it - so they can also hold their teenage lover in contempt at the same time.
Of course, it only works on a frustrated, immature teenager, because a man would tell the woman to go to hell for being a manipulative bitch - and they have, which is what the Feminist Leftist women use to tell the liberal women that men are evil, in order to let the liberals off the hook for being manipulative bitches.
So don't believe the out-of-control crap. It's all highly controlled, understood, reinforced and executed like a military drill by many, many vicious, heartless, monstrous females, in order to traint themselves to desire power instead of love, and convince themselves they hate the very men they are torn apart wanting to love them.
The liberal mind: a garbage heap, on fire, dripping acid, laying waste to all around it, crying out that it is a victim.
The Leftist mind: The creators, maintainers, and users of groups of liberal minds, for their own private political and financial purposes.
ALL teachers are liberal women? You mean there are no male teachers in the United States? That’s the stupidest post I’ve seen on here. Clearly, liberal women make up a disproportionate amount of the teachers in this country, but not all teachers are women and not all female teachers are liberal.
