The so-called mystical or religious aspects aside, I think parents need to observe the sensei (teacher) and the class carefully. My daughter was drawn to karate as a kindergartener because of cartoons and action figures – she was a tomboy. I finally relented and enrolled her in class when she was eight. The discipline was helpful – and she gained some confidence in herself because the sensei complimented her a lot. In practice, kicks, etc. were usually done in the air toward imaginary enemies, and the students would be helped as to form, using strength, etc. But then there was sparring. Yes, they’d wear pads on their legs. But it didn’t feel right with me when my daughter was complimented for knocking even older/bigger kids down during the sparring … but I didn’t say anything. But one day the sensei taught them a move in which they would use fingers to claw the eyes out of their opponent. The sensei complimented my daughter on the strength in her hands and fingers (backed up by strength emanating from her back and shoulders). He then had them partner up. My daughter fainted. I took her home – and she said she never wanted to return (and of course I didn’t make her). She had nightmares about hurting others.
The sensei may not have intended to specifically preach against Christian values, but in my mind, my daughter’s experience WAS very unChristian. The sensei failed to teach that these moves were for defense in the event of danger, only. And even if he had taught this message effectively, kids that young simply can’t handle all these thoughts about danger and violence. I wish I had been more prayerful and discerning about God’s will back then. I think if we had seen Jesus in the room, He would have said “STOP THIS NOW. This is not about love.”
When my daughter was a teen, we talked about the importance of safety and self-defense – and yelling at the top of our lungs, and running during perceived danger.
