I was discussing with a person the issues of contraception. He wanted to have a "non-religious" argument. Mid way through the conversation I realized his "non-religious" and my "non-religous" view were different. After him accusing me of using religion in the argument, which I never did, I asked him to clarify what he meant by "non-religious". This is how I phrased the request.
"Non-religious," do you mean scientific? Do you mean atheistic? Can an agnostic enter in the debate? What about the Humanists? What for the people who are spiritual but don't claim religion -- can they participate? I know of many different religions, but I have never heard of a "non-religion" in our world of which that has been qualified, so that we can have such a "non-religious" debate about something such as contraception. Because there are no "non-religions" we can have no "non-religious" arguments. Therefore the only argument can be a religious argument. The question is, which religion do you want to use as your basis for your argument.
