These “concerns” about socialization are the result of propaganda to a receptive audience ie. working women. They love thinking that dumping their kids in daycare and public schools is good for them.
The homeschoolers I’ve interacted with are better socialized than the institutionalized kids. Their manners are better and they are more curious than the other kids. (I teach a CCD scripture class to 12 year olds).
Most homeschooled people I have interacted with are better behaved, better educated, and are not indoctrinated to be “woke”.
