What has Christianity truly contributed to humanity

[Angrboda]

Denying the obvious just makes you foolish.


Since the point was about the falsehood of your statement, and not any trait of Buddhism, this is a nonsequitur.  It's irrelevant.  A red herring.

False on both counts. 

Let's examine them more closely.

"The genetic fallacy is the act of rejecting or accepting an argument on the basis of its origin rather than its content. Under the genetic fallacy, we judge a claim by paying too much attention to its source or history, even though this criticism is irrelevant to the truth of the claim."

Citing Christ on Christianity or Buddha on Buddhism is not a Genetic Fallacy.

Now you're just blathering nonsense. The genetic fallacy occurs when you validate or dismiss something that follows an origin based upon the qualities of the origin. All that you're showing here is that you don't do logic well. But then, I wouldn't expect a mere money changer to know anything about the divine science of logic. And the second is so obviously true that you have to be crassly dishonest to deny it.
