If you are sincere atheist then Christianity shouldn't bother you. In fact, you should be encouraging as many as possible to be Christians. You'd want your neighbors to be taught to love you, help you when your sick etc. All you'd have to do is put up with a little bit of occasional witnessing. Do you repent? Sure, but I'll pass on services this Sunday.
I know too many True ChristiansÒ to ever trust one with anything I hold dear.
