What kind of difference in society do you think you are making here? Do you think this person is unaware there are people out there that think religion and faith are bullshit? Like do you honestly think she has never considered that fact until your harassment? I feel like that's not the way to go about that. It's pretty juvenile. I have all sorts of contact with people who run the gamut of religious, political, and philosophical beliefs and somehow can have honest and open conversations with them without sounding insulting or coming across like an asshole. Honesty doesn't make you an asshole. Your lack of maturity and tact do.
