There is no age at which it is inappropriate to listen about these extremely basic facts of the world.
At least in my country, what the GP is saying is almost the precise opposite of how the pupil-teacher relationship is conceptualized. Indeed, people often bemoan teachers who just think they're providing a service, instead of taking their responsibility as mentors seriously.
Just to be clear - an informed electorate is sort of key for American Democracy so openly arguing against any form of education is a pretty clear argument against some really basic tenants of America.
In the broader context this topic would be dull as dishwater and boring as toilet training if a certain type didn't make it interesting if only as a measure of their obsession with sex and other people's mere existence transgressing on useless norms that they somehow assume are vital to our society.
Outside of your fantasies teachers aren't violating your kids boundaries by having a same sex partner or a last name nor yet by telling them some households have two mommies or two daddies. What you are actually concerned about is constant exposure to reality may lead your kid to believe that its normal and acceptable for a man to love another man or a woman another woman which is ok because a substantial minority are gay and it is indeed ok for them to love whom they love.
Instead you'd rather in your words "destroy public schooling" one of the most obvious wins of the modern era to avoid... your kid learning about... adam and steve.
The number of people home schooling went up during the pandemic but it is a single digit percentage not spreading like "wildfire". I expect home schooling to be sufficient for only a minority while a larger portion might well benefit from a partially or wholly online experience.
My kind is American or more broadly Westerner I suppose and I was not aware of any effort to conquer me.
Would it have been inappropriate if she said her and her husband was having a baby? In todays society would it have been in appropriate if she said her and her wife? How do you think these same conservatives would have felt if little Johnny came home and mentioned to their parents that their teacher spoke about her wife?
and by their definition that somehow topics around queer people & gender can be inappropriate; this is not sex education and no, nurses are not handing out hormones to pre-teens.
Many of these laws specifically enable people to sue teachers, governments, officials, women who had an abortion, etc.
That enables conservative & religious fanatics to have the last say and impose their moral worldviews onto the rest of us.
The fact that gay people exist is not 'appropriate' in many of their minds. Which is gross and sad. And therefore these laws give the vocal minority the power to force the rest of us back into the closet.
