I'm a college professor. Thankfully, no one tells me what I can or can't teach, and if they did I would probably resign.

when in an instructor role, i typically teach one-on-one, for about 15-30 min at a time, a few times a day per student. this way it's easier to convey the true knowledge, discover flawed logic and learned lies, and help the students to unlearn. i like the opportunity to give and receive frequent feedback and questions. the downside of this approach is that i can only teach a couple people on that day.

I am looking forward to homeschooling in the future.

This is kind of a hard question to answer. If you have to teach a certain material the school gives you, of course it is biased in some way. Only if you have 100% control are you able to control what is taught. But if you are in 100% control, arent you brainwashing towards your biases?

I'm not a teacher and I could be but I decided not to for the same reason.
