Ian & Gary, referring back to the response you made to my post of the Penn Jillette video, I don't think atheists can be said not to be proselytizing out of love.

The Bible tells us that if you do not believe in Jesus as the Son of God you will spend eternity separated from the love of God, in a place called Hell. Therefore, Penn's point is that, if you truly believed that, which Christians do, it would be an act of love to warn non-believers. Of course, this must be done in a gentle loving way, giving people the right that God has given them not to believe.

If the Christians are wrong in their belief in the Word of God, they have done no harm to the non-believer. The non-believer goes into nothingness as they expected anyway.

In the case of atheists, if they persuade others not to believe and they are wrong, this person is now sentenced to eternal damnation along with the atheist.
