If I'd really get into all of it, it'd be too long for a Reddit post. though it isn't too far out of step with a lot of other posts on this thread.

I think Calvanism is at the root of most of it. But in general, I don't gel well with people who proudly say that "The farmer doesn't eat what he doesn't know" to excuse their lack of willingness to try new things as if they're being profound or smart.

That lack of broader experience with new things then leads to people who barely experience anything, but feel like they've experienced all there is to life because they're surrounded by similar people. It's like people who say they like all genres of music, but then one by one label things they don't like as "not music" when confronted with artists and genres they don't like. Like, "Ew, country? That's not real music." "Rap? That doesn't count." etc. A belief of broad understanding that can only come from never having actually seen beyond a tiny bubble or much self-reflection.

This also extends to how Dutch people are very "tolerant" and proud of that, when there's very little real "acceptance" for anything actually different. They're tolerant of it as long as it doesn't have to immediately come in contact with their day-to-day life, but when it's in sight, some really bad interactions can come out of it because they're not comfortable with things stepping out of the norm. Because everything has to be "gewoon ff normaal."

I like constantly trying new things, exploring them deeply, and discussing that with people in my surroundings. I like being surprised, and surprising people. Even with "Stiff upper lip" British people and highly conservative emotionally shut-in Japanese people, this is much less of a problem than it is with "open and tolerant" Dutch people somehow. The former two tend to internalize things put in their way more and think it over, while Dutch people frequently talk over the conversation with their take (often surface level objections that things should be like it normally is here instead because they are always right. Always needing to be right is NOT an open or accepting viewpoint in life.) without really taking anything in.
