As to your statements, yes, real high school level physics. But a very condescending thing to say to someone trying to understand.
As for how a stem riser attaches to a stem, and if this is going to cause another apoplexy than please, just stop reading and block me, but I don't follow your reasoning. The few I have used all attach at the top of the tube in exactly the same fashion as a stem. They have a stop about an inch or two in, require spacers, have provisions for pretensioning, and clamp with two clamping bolts along the length of insertion the same as a stem. None I have used have a sharp lower edge.
found this interesting. An explanation without all the drama

Please, you already called used the word "ignorance", so please stop sounding wounded.
Yes, you don't understand how the clamp on a steerer extender works - and even when I explained to you the difference you persist. If my description isn't enough for those gifted in high school physics to understand, what would?
It's a bad idea, and the fact that you can't understand why and have no experience with either carbon OR extenders doesn't make it okay for you to try and convince innocent third parties to do something super dumb because you think it is all simple.
