Dear Melanie,

I find this statement to be offensive:

A simple "God Bless" or "May your God go with you" would offend no-one. They are non-specific, polite, and equally apply to whatever Deity you happen to believe in. And if you don't believe in any, then remarks such as those are pretty much unoffensive.
Why should I be forced to acknowledge other people's gods when one of the foundations of my faith is "Thou shalt have no other gods before me"? Why should I have to water down my faith to please other people?

I find this statement to be bullying and offensive:

It's all down to politeness and behaviour in a wider society. Polite people would moderate their message when it has been pointed out to them. Die-hard religious types I suppose will continue to broadcast their missionary statements to those who would rather not receive them.
Who made you judge of politeness? When I find a post or signature offensive, I ignore it. That would be my definition of politeness. Your definition of politeness is censorship of anything you disagree with.

Please God, these quotes are specific enough for you.

May God bless you,
David Cullen
