but there's a reason why stereotypes exist

I thought that reason was ignorance?
Tell us why few women are here.I did.
If women are equal to men in every way, then WHY aren't they represented equally on this forum?
I'm not sure what "equal to men in every way" means.
He's right -- stereotypes exist because they're true 90% of the time. Plain and simple.
Including most racial stereotypes?
Seriously how do you determine 90%? What sample did you use? Was it well randomized? What is the size of the population?
Congratulations, this is one of the reasons I think stereotypes exist. People's brains want to see patterns and they suck at statistics.
If I started stereotyping Americans as people that like to drive their cars into trees, the stereotype would die pretty quickly because A) it's stupid B) it has no basis in reality.
So it wouldn't catch on.
So in your mind, because one potentially false stereotype fails, most stereotypes can't be false? Outside the US there are plenty of stereotypes about Americans - are all those true?
