Is it normal to agree with stereotypes

One of my close friends is an AA woman who is a lawyer and has a masters in social justice. One of the dumbest people I know happens to be asian and he does not understand math whatsoever. Meet more people.

Well yeah this is true to a point. However its racist to say all japenise have tiny penises or all black people are automatically very stupid. I do believe that certain races are going to be better at certain things though.

Stereotypes is Stereotypes, it's how people use them is the problem.

I disagree, believing in a stereotype is judging a person without any context besides what can be physically observed of them.
You are assimilating a lot of raw data and coming up with a conclusion far too early. You will lack respect for people and you will lose your humanity, to the extent you actually believe in stereotypes.
My advice is: next time you meet a stranger, treat him completely different than you would based on the stereotype.
(I tried this on my latest trip to Turkey, where I totally humanized a local broker, and we had a great chat, even though at first he was out for my money, like many tourist preying sellers over there. You will be surprised!)

What you need to do is work on getting to know a rainbow of people. Once you have friends of different nationalities it's hard to keep believing your ASSumptions.

A human will either consciously or unconsciously conform to others in their community who they can identify with. Therefore, people tend to become the stereotype. However, this image that they portray really says nothing about them as individuals apart from their perceived need to conform. Physical stereotypes may or may not have credence. For example, you could say that the common stereotype for caucasians is that we have lighter-colored skin than blacks. This is obviously true on average. However, other physical traits such as penis size or muscularity can vary so much WITHIN each ethnic group that comparisons BETWEEN ethnic groups are pointless. Intellectual comparisons are equally pointless for the same reason.

there's more to any one group than a casual observer might suppose.

Hmm, that got me to think about the difference between audism and racism. (I'm deaf btw, which is far less common than what you would normally see) I'm gonna to disagree with what you believe because too often, from an area where I live at, latinos seem to be so interest in cool car that is actually use for family, and black dudes get all of cool clothes, pants, hats, whatnot. That is positive stereotypes. I don't know about Asians, but that is what I would say it's normal to agree with people.

Oh, and about dicks... lol. Check out dudes' in southern Asia.
