Why most African Americans have bigger weapon?

Besides the fact that you stereotyped so bad, your question is barely comprehensible so it's hard for anyone to answer. Though it's true to a point that African American males are larger than other ethnic backgrounds, they only surp the other averages by about 1/2 to 1 inch, depending on the chart in which a person uses to compare. Just because African American males may be a little large doesn't mean a white woman (or any woman) would like to have with them. This again is another stereotype. Some woman do have with a man for his size, but that doesn't apply for all females. Don't stereotype people because they do not apply for everyone. Hope this helps.
