Let me add a few more things.
4: That there's no dichotomy of "Worshippers of God vs Worshippers of Other Gods" When i tell my friends and who are still in that I simply worship nothing, they draw blank faces. They think you worship a God no matter what you tell them. There have been godless societies before ours and there will be godless societies after ours.
5: That perhaps there can be a counterpoint to their points.
6: That they always come off as arrogant blowhards.
