I didn't downvote the comment, but I would have done so. If we want to talk about how discussions
should work then the commenter should have first spent two minutes researching and/or explained why sources like the Associated Press (my first result when copying and pasting the comment in DuckDuckGo) aren't reliable.
"I don't understand" is a good way to foment discussion. "I don't believe you" usually isn't.
