I'm German myself, and luckily I haven't heard "polen" so far (Edit: Might be because I live next to France not Poland). But a lot of my classmates make a lot of kinda racist jokes about the AfD (right, potentially extremist political party) and I can't tell whether they're actually racist or not.
I dislike the US power plug way more than the Europlug (or compatible sockets like Schuko). It just slides in, only thing holding it in is friction. Also, there is a connection while the contacts are exposed, exposing the user to the risk of shock.
Also, I like DisplayPort more than HDMI, it clicks really nice on insertion and in my opinion pulling it out is also more satisfying.
I don't hate it, I really want to like it. It's just that I have a rather niche issue that really bugs me and forces me to chromium (or derivatives).
FIDO2 / YubiKey support on Chromium is far superior compared to FF.
