I have long been concerned that homeschooling would result in kids that were not well socialized due to not attending school. Perhaps I was wrong to worry about that.

Virtually every homeschool kid I know is plenty well socialized. Most homeschoolers have problems trying to curtail their extracurricular activities.

If you think that the kind of socialization that kids get in public high schools today is a good thing, you need to really, seriously, strenuously, reconsider your position.

No need to even respond to the “socialization” argument anymore.
If you want to be direct, simply state that you know what their real objection to homeschooling is, and it’s not “socialization” -

it’s that the kids aren’t being indoctrinated in the secular humanist worldview,

so just “cut the crap” about “socialization”,
and let’s discuss your real issue, shall we?

Now, just imagine whom you would like to say this to and smile.
