It's a pretty unnuanced criticism to complain that critics are just whiners. At the very least you could explain something he was wrong about instead of pointing at tone.
Obviously he's not a 'gullible mark' if he's actively seeking scammers to highlight on his channel, how is that confusing for you?
Congrats to your first comment here on HN, even if I see room for improvement. Like writing something intelligible for example, always a good rule of thumb.
