I dont understand your problem. People say that when experience and logic unfortunately causes them to acknowledge the validity of a stereotype without an emotional malicious desire to do so.
Example: Im not trying to be racist, but why is it that pink people are usually so loud in public places when green, yellow and purple people usually keep their voices to a moderate level, certainly after the age of 25? I wish it wasn’t true, but experience has unfortunately caused me to see the validity of this stereotype of pink people.
