First of all, always making clear that belief is just that - what someone believes, and there are many others believing many other things.
There are many different mutually exclusive religions all claiming to be right, except for maybe one, they cannot all be true, and even the one that might be is probably not.
And as much as they don'#t want to be bothered by my views, I don't to be bothered by their views.
Also, they bloody well shall read what Jesus aka the Saviour, the Lord's son or manifestation or ... whatever it was... actually said, e.g. the Sermon on the Mount etc, and then think a bit about their behavior in the light of Jesus's words...
