Some pretty good thoughts, but why shouldn't their children be allowed to attend our schools? In your preceding paragraph, you say children shouldn't be punished for the sins of their parents. Wouldn't this be the same thing?
I had the same problem installing my daughter's with a remote. Turned out the receiver inside the unit wasn't getting signal. Had to drill a small hole in the casing and poke the receiver's little antenna out. It works fine now.
