I don't care about your friend or where he studied.
Your trying to escape and avoid the main point.
It's biased and holds malicious intent, nothing on that site is representing both faiths equally or objectively. It's coming from a bias of malicious intent and spreading false misinformation to push his narrative.
Now I'm asking again
"let me ask you this, if a random man, wanted to learn about Christianity from authentic sources, and there was a website taking bible verses and words and teachings and the biography of Jesus out of context, and then creating their own interpretation. Or there was a righteous Christian man or woman, with authentic Christian sources with full context and understanding.
Who would you want that random person to learn from?
Why would you go to a source of misinformation?"
