Their book is a load of piffle, and I am not a believer.
However, I have had to attend various religious ceremonies over the years, mainly christian church services.
I have never heard a sermon or message delivered that suggested intolerance or damnation for non-believers, services of all faiths that I have attended have focused on the principle of being nicer to each other, if you’ll excuse the oversimplification, which is not a bad message to put out, regardless of any supposed heavenly reward. To imply that all religious belief is somehow wrong strikes me as rather missing the point of the various assorted flavours of fairy stories involved.
Early post to invoke the Hitler rule, fair play 😉
