Fat is still bad in excess, you are just stuck in a different meme cycle where Americans pretend it doesn’t matter and surely couldn’t have anything to do with the rampant obesity.
Hang around on Reddit for a day or two and you'll see them. Or heck, remember the Atkins diet, which was explicitly advertised as "you can eat as much fat as you want"?
The meme version of it does, and their official website gets pretty close - fat is unrestricted, it's fine to eat as much fat as you have an appetite for, it's fine if a large proportion of your calorie intake is saturated fat. I guess "to excess" is subjective, but Atkins certainly says that fat consumption levels that respected medical authorities say are dangerous are fine.
