Well, you stated being direct and blunt as a negative thing for the friendliness meter, which isn't necessarily true. it's also a small thing compared to the bigger picture i was getting at.
what you should look for here, is how we treat people, how open we are, and how mindful of each other we are, comparing us to other countries. that's what people view for ''friendliness''.
on that chart, we score hella high. we are considered really nice people. Yes, i also know a lot of dutch people who are rotten apples and not nice people at all. yes I don't like a lot of my fellow countrymen actually and don't think as highly of them myself.
however, my personal bias isn't important in this point, as the generic point is different.
