I agree with you, freemindfade, there are lots of bad ideas in religions, whether it's ISIS beheading a street magician, the OT jews stoning some poor sod for collecting firewood on the Sabbath, or JW parents refusing a blood transfusion and looking on as their child dies a painful death.
OTOH, I suppose religious beliefs often help the believer through the ups and downs of life and provide a moral framework. As long as religious people act within the law and don't harm themselves or others, religious belief should be tolerated, IMO.
Let's face it, religion probably won't go away so it must be tamed.
