OP should have his daughter start a Christian club and invite pastors in to present the gospel to kids who may never otherwise hear it.
In fact there are entire church ministries centered around that very concept.
A handful of churches in America eventually wised up and realized that wringing their fists in outrage and hiding from the filthy heathens(such as op is doing) wasn’t actually helping anything. Rather they realized their kids could start clubs in public schools just like the satanic kids and lgbtwtfbbq kids could do. So they decided to drop all the nonsensical defeatist homeschool/private Christian schools rhetoric and sent their kids to public schools and had them start Christian clubs. Now they can have pastors come in and give Godly council to kids and present the gospel to them.
14 Ye are the light of the world. A city that is set on an hill cannot be hid.
15 Neither do men light a candle, and put it under a bushel, but on a candlestick; and it giveth light unto all that are in the house.
16 Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.
Stop hiding your kids with homeschooling and Christian schools and go be the light of the world.
A lot of times Christian’s like to blame the world for kicking God out of school but in reality it’s more along the lines of the world saying: Hey we don’t like God and Christians responding by taking their kids out of school and taking God with them in the process.
