I think having good taste is a requirement to begin with, but it's clear that their diets full of extreme flavors and sensations are destroying their ability to taste anything more subtle
Look at any online image of a guy cooking something really simple like a basic pan fried fish with salt and pepper or anything like that that doesn't require large amounts of seasoning and is just a quick easy meal, and you'll realize by the instant anger and responses demanding DA SEEZNIN that a lot of these people literally do not have such a concept as a 'quick easy meal' that 'doesn't require large amounts of seasoning'
They even took it out on a video of a little child eating a bowl of basic pasta, for a group of people coming from such a starving land they sure don't seem to have a concept of eating just to sate your hunger and not making everything a presentation
They never just grab a quick salad or put together a sandwich or just boil a nice egg, unless their food is a snack item and comes in a box, everything they *prepare* must have tons of seasoning on it, likely to mimic the stuff that DOES come in a box
Eating a crazy hot dish with tons of spices only has that kick if you recall eating something that isn't like that, but if you literally never do, it'll all start blending together and anything lighter will feel bland
It's like people who eat nothing but super sugary snacks all the time and think fruit don't taste like anything
