Jews have the same problems Christians and every other sect has. Some follow every jot and tittle, and others, not so much. If you choose a tat after you know it's forbidden, it's not so much the tat, but your attitude towards God. The Law isn't explained, but it probably has to do with idol worship or God figuring you look like He wants you to look. It may even have to do with pagan ritual, as most pagan religions practice the art.
I agree...but a lot of folks have a 'good attitude' towards God, but do wholly their own thing. I suspect we are on the same page...
