B. The "role playing" vs. "roll playing" debate. This is now more than 40 years old, and I don't think we will get very far in this more recent iteration. I do think that there is an interesting conversation to be had about the appropriate boundaries regarding roleplaying (similar to what we have seen with acting), but I do not think that the way that this thread has presented itself makes it an ideal topid to explore that discussion.
I would say that most tables I have played at that have been heavy into "role playing" to tend to incorporate the physical abilities into the character conception, and that we have the same divide. In other words, people who aren't taking the physical abilities into account for RPing say, "Look, we don't do this for the physical abilities, so why should we for the mental ones!" While the people who do it for the mental ones say, "Look, we do it for the physical abilities, so of course we do it for the mental ones!"
Two ships passing in the night.
