In the human language, one sentence can mean something different with one word or punctuation. This was a comment made in a speech. A comment which was spoken. Since this speech was not written the actual context of the sentence is left to those who heard it to interpret.
Take the following two sentence for example:
My grandmother was a typical white person. She admits that she gets nervous when she sees a black man. (The period suggesting two separate thoughts, not connected.)
My grandmother was a typical white person, and she admits that she gets nervous when she sees a black man. (The comma suggesting a pause in thought, but one thought.)
On the other hand, the terms given to blacks, hispanic, asians, or any other group of individuals is not to be mistaken.
In short, to cling to the word "typical" in a sentence, for which it is unclear as to what is being considered "typical" is stretching. If that's the only word people had to be offended by, I would happily be called "typical".
Update: To answer rsbobeenie yes he is, I am a typical black man, my white step mom is a typical white woman, because no matter the color we are all typical of the United States of America.
