Not common enough that I have ever heard of such a thing. They aren't coming to get your guns or bibles either. And when compared on the basis of standardized populations and other factors, there is no statistical advantage to private over public education.
This is dishonest. Nationally, the outcomes may be the same as an average. However if you live inside the district of a bad school, you will then appreciate a private school. A private school that has poor success rates goes out of business. Public schools that have a poor success rate send graduates high schoolers to remedial classes in college. It is very rare to hear stories of the worst

Also if you are an involved parent, you can influence how teachers teach a lot more in a private setting. In other words if your child has a crappy teacher in public school, he or she may not get the best education for that subject and there is little the school can do about it because of tenure etc. If your child has a crappy private school teacher, they are going to be much more receptive to the parents voices. As was the case for my son.
Also I am not a religous person, but there are many things public schools cannot teach that private schools can. To you an me, this form of education may be wasteful, but to others it may be important.
My personal experience, I went to both private and public school. K - 1 in private school. I was learning french every day, was able to long divide, learned script, I remember a science experiment where we learned about the meniscus of water in a graduated cylinder and the sticky properties of water - how many pennies until the water comes over the edge. In High school after we moved, I spent 10th grade in private school again. I was behind the rest of the classmates. We were
making recombinant ecoli DNA and running it through agarose gel, we had a physiology class that involved the 4 week disection of a cat. We had an economics class that involved studying companies and applying matrix formulas to earnings.
You are quite off base here, and are only repeating talking points without critically looking at the information.
