Hire really smart college kids as tutors if you need to for the math and science. Use homeschool textbooks and materials. Use the summers to move the kids beyond the public school level of math and science.
And finally, make jokes about - in the way of a lesson of exaggeration to demonstrate silly politically correct nonsense you hear from them. Use the double standards about race and sex hate liberals use and how intolerant the tolerant ones are. Teach them what happens to people dependent on government handouts. Make fun of nasty RAP lyrics if you hear them playing that nonsense. Watch commercials with them and get them to learn what the manipulative message is. This analytical ability will later be useful for them to grasp manipulative socialist messages.
It’s really not hard for kids to see the inconsistencies of liberal thinking. They’re certainly smart enough and often not brainwashed enough.
And kids just HATE hypocrisy.
For all the criticism of how homeschoolers are supposed to be so *sheltered*, we, and everyone in the homeschool support groups I was in, weren’t. We were constantly exposed to liberal thinking processes from kids in the neighborhood, kids on the swim team, relatives, stuff on television, etc. That gave us plenty of opportunity to discuss PC nonsense and expose its flaws.
Getting an accurate view of history is important so we can learn from it. Those are good suggestions.
