I personally, wonder whether anyone in this thread actually plays this game for fun or if they just care about roleplaying.
For some of us those two things are identical.
No disrespect, but personally I find making people happy and solving world hunger more important than pretending to be an elf with other adults.
No disagreement there, which is why I choose my day job and many other aspects of my life accordingly. However keeping myself sane and reasonably happy is a large part of staying optimally able to be productive and positive in those other spheres, and for me roleplaying is a major cheering element in my life.
Playing a bunch of different perspectives, with different moralities, and - perhaps most important to this particular discussion - different degrees of capacity and agency within the RPG universe (referring to that as "viability" seems an over-simplification) and interacting with other people doing the same, is an ongoing contribution to broadening my understanding of and ability to empathise with a broader range of people in the real world. So yeah, I will defend my roleplaying as positive in intent to the broader world, and encourage others towards it on similar grounds. (And that is specifically "encourage", not demand or dictate or anything like that save within the context of negotiating the particular social contract of a game I am personally involved with.)
The maths involved in Pathfinder, on the other hand, is arithmetic and probability on a scale I was reasonably competent in thirty years ago in school and only occasionally have use for since, so there is only so much benefit polishing those skills by min-maxing is to me, even if I did find it fun.
