Most Everybody Draws A Line Between Thier Desires & Moral Principles

Almost everybody draws a line somewhere between their desires, cravings, and feelings; and moral principles.  Almost everybody has at times a desire they want to fulfill, but they intentionally restrain themselves because they believe that fulfilling that desire is morally wrong.  We just draw the line in different places.

So how can people who draw a moral line at intentionally harming a child after it has been born, call those who draw the moral line at intentionally harming a child in the womb, judgmental?  Both are holding to moral standards about how to treat human life.

And how can people who draw the moral line for sexual expression at orgies (or rape) call those who draw the moral line at sex outside of biblical marriage, intolerant?  Both are denying sexual desire because of morality.

And how can those who make their own decisions about where they personally want to draw moral lines, condemn those who accept the moral lines drawn by the Bible and acknowledged almost universally by moral leaders of various cultures through out history?
