What has Christianity truly contributed to humanity

[Anomalocaris]

And to you, Anom, I reiterate: "Only Jesus Christ has expressed clearly, concisely, perfectly and precisely that these Two Commandments summarize the Whole Duty of Man and Woman on this Earth and are the Foundational Precepts of Religion. Only Jesus Christ has taught one should love even one's enemies and pray for those who persecute you and bless those who curse you. And He did it too on the Cross. Greater Love has no Man than [this], the Just Son of God most beautifully said, than that He should lay down His Life for His Friends; and yet, He had a Greater Love than even that in the Goodness of His Sacred Heart, for He laid down His Life even for His Enemies. One would have to be almost insane to not be able to see Jesus Christ was, at the least, a Good Man, and One of the Greatest Men to ever have existed, following and practicing whose teaching can but lead to human flourishing and human happiness even in this life."'

strip away the ridiculously contrived and exorbitant hagiography that any cult would armor its godhead with to disguise its own overeach and vacuousness, and what still might be said to remain of the figure Jesus is most certainly not discernibly a good man.  He was not discernibly better than any of the self absorbed, self-important, manipulative overreaching bum with delusions of grandeur, not discernibly different from what are dime a dozen in the margins of most societies, especially prevalent in societies with deeply ingrained sense of superiority that had been rudely shattered by confrontation with reality.    And this no good manipulative layabout with delusions of grandeur, like so many others of his kind he, through his own misdeeds and insanity came to a miserable end.    
  
It was only the deeply unfortunate happenstance, occasioned to fatally dovetail with pervasive gullibility his uneducated peers and through the mechanizations of various actors with different, all discreditable motives,  that led to his becoming elevated to some sickening avatar at the head of your ridiculous cult.    That such a chain of event could happen and could dominate such a significant portion of human society for 2000 years is the greatest disgrace in the history of men.
