I have news for you - we are ALL NOT THE SAME and we ALL COME FROM DIFFERENT BACKGROUNDS - and those backgrounds shape who we are - hence those backgrounds and culture will certainly stereotype us.
If you can't see the differences then you have blinders on - weather it's due to politics, lack of observation or just plain ignorance.
There is absolutely nothing wrong with realizing traits - traits that belong to certain ethnic groups and cultures.
People being offended or not is irrelevant!
Racial stereotyping is bad for society - end of story.
