Why they home school him is completely irrelevant.
Of course it's not.
Taking kids out of school so the parents can force feed them Christianity is certainly more "abusive" than taking them out so they can focus on a singular talent?
What's your question? Both are abusive.
That barely registers on that scale.

Hell, the argument could be made that sending him to an elite private school is more abusive.

Kids should be encouraged to play as many sports, and have as many activities, as they can enjoy when they're younger. Pulling him out of other activities to focus on just one, at age 11, is borderline abusive. Then ripping him out of school, so he can focus more on this game ... that's definitely abusive. This kid is more likely to not develop, get injured, get burnt out, etc. than he is to have any meaningful success at golf ... and they're making him sacrifice his childhood to play this game.
