The OP asked if there were any believers. If you aren't a believer, why pop in? Is it just to argue with those who are? Talk about "immature and irrational".
Yawn ... too many years as a JW makes you crazy.
1. Their emphasis on the Mosaic Law is irrelevant to Christians. It doesn't apply. They do it because that GB has decided Christ is only for a few, so the rest get Moses.
2. Whether you think the God of Israel is cruel is subjective. It depends on whether one was a Jew or a Gentile (particularly a Canaanite).
