To be fair stereotypes didn't just come from nowhere they are typically just repeating observations of cultural behavior and don't necessarily have anything to do with race
modern people are just so hyper sensitive and aware of it because they've been raised to believe "racism bad" without any real critical thinking put into it and when there's no obvious actual racism any opinions or observations about a cultural group begin to look like "racism" to the modern person and when most people typically try to hangout and build a community around those that are like them in some sense when a person makes repeated observations about them and when those people have a distinguished physical trait it suddenly becomes "racism"
example "in my personal observations Hispanic people are very family oriented and love to have big families and they love to get together as often as the can for family gatherings"
Now is that racist? No its simply an observation of "Hispanic" culture but it is similar to "in my personal observations Hispanic people must love rice and beans as they are common side dish in their meals" which many modern people would for some reason believe to be a racist statement even though it's literally just an observation of food that a cultural group commonly makes
Or another "in my personal observations black people are very expressive with their emotions" is this racist? No because I don't actually believe it has anything to do with their race or genetics simply their culture it is literally just another of my observations of another cultural group and I simply say "black" as that is more of a cultural group here in the US
I would probably be branded by many people a racist for such statements too bad for them I don't actually care what people call me anymore
Well, the problem is that you were able to make an observation.
Majority of people cannot.
Like, they physically cannot, they live far away from a community and never get to interact with them
Hence, the only way these people get to even know about these far away land communities is by seeing media.
Example, for decades, my country believed all women in America walked around in bikini all the time, because Hollywood movies of 90s were full of that stuff.
Or well, there was this one time when my friend found a fake news article talking about how Chinese eat aborted foetuses for nutrients; and he immediately believed it and shared it with others.
Why?
Because media shows them that way.
Like, I am positive many people would not believe that China actually has a proper cruising. Way too many people believe their sole diet is insects.
Same with Russians! Everyone who hasn't interacted with them thinks they survive on vodka while shooting bears
It isn't practical to say, "stop believing everything you see on internet" because for these people, there is no source of information which disproves these stereotypes for them.
