There are close to 2000 members, and I have no idea how many guests. I'd guess many of those take statements from here as fact. Some probably do not understand the physics and fomulea that describe what is happening. Some are students that are, may or will be taking physics and engineering courses. They should question statements until they are throughly convinced the information is correct.
I'm merely pointing out that everyone here that said it does not happen is technically incorrect.
I do agree though that for practical use it could be ignored.
Here is a link to some simple free body diagrams

I'm not argueing your point and a good point it is.I'm also saying that when something such as this is discussed in this exact context there is no appreciable torque reaction that should be considered .I think the practical is what is being discussed here and not the infinitely analyzed to the last decimal point conclusion that for all intents and purposes is not relevant. For this particular discussion I think you agree that any torque reaction that you are talking about is totally irrelevant.
