I feel like your article demonstrates...everyone is a slave to something. We're bound by human nature. We can't go beyond our natures. Protestant view...human nature and sin are the same thing. Our desires have dark inclinations due to fallen natures. Essentially our wills are bound to our natures. Thus we will choose those things we dare not say in public. This traverses every aspect of our lives. It doesn't mean we are as bad as we could be, but it does mean we're imperfect fallen "sinners".
