How to use a Diode

Finally! A video I can agree with on diodes and the direction of their current based -- not on what everyone else is saying, but -- on how a diode is connected to the power supply. EGADS, can't anyone get anything right?

I posted the following comment on A simple guide to electronic components:

"I'm shocked! I had to watch three videos on YouTube -- this being the first of the three -- before I could hear someone say that current flowing from the cathode toward the anode across a diode is blocked. I remember reading somewhere that this assumption began way back in the 1800s by physicists incorrectly deducing that the electron was the passive component of an atom (yin) and the proton was the active component (yang). Since they recognized their error fifty years after it began, they decided it was too late to correct it. I just assumed that everyone knows this by now and no longer makes the same mistake? The tell tale sign is: which side of the diode connects to which terminal on a DC power supply? If the diode's cathode has to be connected to the negative terminal on a DC power supply, then that means that electrons are flowing against the diode's arrow. This also implies that voltage builds up across a diode if current is forced to flow in the reverse direction from the diode's anode towards its cathode by connecting the diode's anode to the negative terminal on a DC power supply. Or am i misusing the term: 'current'? Should I be using the term: 'amperage', instead? This is so confusing...... Can somebody, please, clear this up? 🤣"
