If you wish me not to be thrown into hell can I wish you a peaceful rebirth?

I am saddened by the Christian who resort to 'hell and damnation' threats in order to feel better about themselves. I wouldn't wish a hellish rebirth on you so I'm wishing you all peaceful rebirths. Now, how offensive do you find this? If you can wish things for me, I feel I can wish things for you and I'm glad to say at least it is a kind wish. Thoughts from believers and non most welcome.....Namaste
