I know Buddhism well enough to say that it was not under attack in the video.
The big divide is reincarnation. If I whiff this life I get to try again next life. If I move down even the lowest form on earth is better than Christian Hell. All just part of their path.
Christianity and related religions believe you get exactly 1 shot. Then either heaven or hell. No in between, no second chances, never to switch after initial assignment at death. That is where her questioning their sense of urgency comes from.
