Oh, and before we begin, let's not put any kind of qualifications on the discussion. It's not necesarily good or bad if one group has or does not have bigger penises. Nobody has to feel good or bad if they have a bigger or smaller penis, or if their group tends or tends not to.
Just, do they, or do they not?
It would be great if you refered to the quotation in the original post. ^
I know this topic has been treated many times on this group.
Let's discuss it from this angle.
By the way, the history, politics, pyschology, economics, and symbolism of race and penis, are generally not within the scope of the discussion intended for this thread.
