So, to look towards the actual question I was asking, halflings are overlooked because no one expects anything from them?
Again, why? What makes you quiet guy who was happy to be a dishwasher more underestimated because he was a halfling instead of a Genasi? Or a human, or a half-elf?
And, you gave a sort of answer to that, halflings "act like Switzerland" they don't get involved... but look at the type of things we are talking about getting involved in. We are talking about things like being attacked by raiders who may want to kill everyone. About Giants rampaging over the countryside. About Dark Gods being summoned to destroy the world. You can't just "act like Switzerland and not get involved" with stuff like that. But those are exactly the scenarios where we are pointing to and asking "where are the halflings?"
And if halfling adventurers are out there dealing with these problems... who is going to underestimate and overlook the halfling people? There is no reason for them to be less important than humans, unless you are only looking at humans who go looking for trouble. Because when trouble comes looking, there should be a fair number of halflings stepping up like you say the fantasy is, and they don't. Unless it is the PC.
I get that I don't need to understand it to hear you saying you like it, but you don't seem to understand why I am confused. And you have no interest in trying to do anything to make sense of this, you are just presenting it as true even though it doesn't match up to the reality of the game.
