What has Christianity truly contributed to humanity

[Angrboda]

If someone says Religion must be false because we have some hard-wiring to be religious beings, that's an example of the Genetic Fallacy. Showing how something originates does not show to be false, as Dr. Craig, the Best Christian Philosopher in the world today in my estimation, has often explained.

Since I didn't do that, this is irrelevant. All I pointed out was that your argument was invalid due to a fallacy.

Next, citing Buddha on Buddhism is perfectly appropriate, unless you want to accuse yourself of being crassly dishonest for doing so earlier. It follows that likewise citing Christ on Christianity is perfect appropriate for the same reason - Christianity means the Moral Doctrine and Teaching of Jesus Christ.

[emphasis mine]

Since I wasn't citing Buddha on Buddhism but rather as an example of someone who had taught a message comparable to that of Jesus, thus refuting your claim that Jesus was unique, I did not do this either and this is a strawman.

This isn't verbal dueling so much as it is you continuing to show your incompetence.
