Mr. Richard Bushey is a young student of religion, a follower of Christian apologetics, and is for all intents and purposes a very enthusiastic fellow. I had the pleasure of stumbling across one of his recent Twitter posts, posing ten questions he has listed on his website -- questions designed to require atheists to be very clear on their arguments or explanations in relation to the genesis of the universe and The Invisible Sky Wizard (my words, not his, obviously). At first, I must admit a strong reticence to even reading them, based on a familiarity with such ploys by the faithful in the past that result in semantically indecipherable hogwash masquerading as logic -- per contra, Mr. Bushey's intro was so genuine in his search for legitimate discussion, and his questions so distinct in their interpretation, that I felt I could not be a gentleman nor a proper atheist banner-man if I did not take the time and effort to provide him answers to the best of my ability. To Mr. Bushey, and to all, I hope you find them entertaining if not enlightening.
JK: No, there is not an objective moral difference between one and the other. In either instance, we are dealing with the civil liberty of a sovereign being. A person, devoid of all exterior or religious influence on their decision, chooses a side solely on which life they think necessitates such liberty the most. The reasons further for such a decision are ultimately fluff because they mirror each other in all things reasonable. Religion intoxicates the argument by providing divine mandate for the choice rather than an objective reason for it, but that can be easily ignored if a follower merely states that they are campaigning on behalf of a defenseless human.
I can't say I'm properly knowledgable as to why this question might be included in your fine list, except perhaps to require an atheist to define their point of moral compass, or elucidate from whence they received it. I don't want to speculate without your input too far. However, I would be remiss not to point out that the subject of abortion waffles widely on both sides of the cosmological fence and many atheists and believers have differences in opinion within their own factions. No matter the answer, it doesn't establish the subjective morality of either side, nor whether an objective, moral standard on the subject exists. I, myself have conflicting feelings about the practice and none of my at-war thoughts are influenced by my non-belief, as I would have to assume they would be not influenced by my belief should I be of the opposite persuasion.
