You're really screwing yourself if you try something that you don't think you can do just because someone on the internet told you you should be able to do it.
Absolutely serious, if they don't think they can do it.
What part of the approach is dangerous? Like I said, I don't care if they land out of it or not, if they bail at the bottom and go elsewhere I have no issues.
"Bailing out at the bottom" can be a pretty tricky maneuver depending on how far someone takes it. There is always continuation bias too. What's the point of trying something you don't think you can do? There are already too many accidents involving people who thought they could do it but obviously couldn't. That's not to say that people shouldn't go out and get more practice to improve their skills, but on a given day if they don't think they can do something they shouldn't.
People crash and burn because they either exceed the airplane's limitations or their own. Part of being PIC is having enough self-awareness of your own limitations to be able to make a decision based on those limitations.
I agree that many pilots need more practice, in fact we all do. However that doesn't mean that you shouldn't use the common sense that you hopefully have and try to do something that you don't think you can do just because some book says you can do it.
I thought that's what we were talking about, someone diverting because of 15 knots of crosswind at their destination.
Inability is really only relative. Sure there are standards but they are also arbitrary. The real problem is exceeding what you think you can do by getting in over your head. Even professionals do that sometime.
Where does it say you need to demonstrate a crosswind landing up to the max demonstrated crosswind component in the Private Pilot PTS?
According to this, it's 12 knots for a C-152.That's why I asked what plane he was flying, and that is all I asked. What plane would one be in where 15 kts is Max?
