You are inferring that all reactions I've seen were all anti-pathfinder.
It's not the case, but I have seen a lot of virulent anti-pathfinder sentiments, or even reaction to anti-pathfinder sentiments, and I wanted to understand the rationale behind this, since I am outside the community where this discussion must have been going on for years now.
I don't play Pathfinder myself, I just kind of know some things about it, and I have no real opinion on the matter.
