"If you are no religion/believer you do not sin, because there is nothing to sin against" agree or disagree
agree....we have morals, values, integrity, and sense of what is right--which may vary depending on the person and situation--but, no... I don't believe that I am sinning, and while a religious cat may say that what I am doing is a sin, it is only a sin only by the fact that he is judging me based on his on belief system.  Ironic of course, I mean doesn't your bible say, "judge not lest ye be judged likewise also,"  or have they removed that section?
"Next the statesmen will invent cheap lies, putting the blame upon the nation that is attacked, and every man will be glad of those conscience-soothing falsities, and will diligently study them, and refuse to examine any refutations of them; and thus he will by and by convince himself that the war is just, and will thank God for the better sleep he enjoys after this process of grotesque self-deception."...The Mysterious Stranger\n\n-Mark Twain
