I suppose there could be many reasons why. Some Christians honestly feel compelled to witness to non-believers as a divine duty.They truly believe they are having a positive impact on those who are lost.
Some Christian theists need constant validation/confirmation because they harbor doubts......kind of like woman who constantly asks "Am I pretty?" Non-believers make them uncomfortable, because this sort of Christian sees the holes in the biblical narrative and it scares him or her. To them it's better to non-believers on board, than sittin' around doing fine without Jesus.
I honestly think the rest of them just love the sound of their own damn voice. Seriously.
