The question about correlation between penis size and race does not clarify what is meant by 'race'. Such vague questions need clarification, or should be closed.
It the answer doesn't clarify the question, we end in vagueness, and I don't think it is acceptable, that the answerer has to clarify what a question means. This can lead to situations, where the answerer has to bring multiple evidences, one for each possible interpretation of the question.
In a few situations, analyzing the possible interpretations of the problem will already debunk parts of it.
The race question, as it is now, encourages the view, that there are 2 races, 'white' and 'black', identified by the rough color of the skin. This precondition is already racism and should not be allowed here, imho.
review after 2 days:
The question still starts with an hint to an unlinked video from which the title isn't known - we just know it is animated and has some statistics. The statistics aren't cited, we are just told, that there are some.
The word 'race' is explained with a short citation from wikipedia, which is cut at the point, where wikipedia becomes critical, and says
But without repeating the whole lot of problems, wikipedia talks about, the definition has already two serious problems. The author cites an alternative (
phenotypical characteristics or geographic ancestry) and doesn't clarify, which of them is relevant, and he cites just a sentence, which describes the usage of the term (
often based on factors such as) - but what was expected was a clarification, how he wants to use the term.
And you cannot answer the question how you want to interpret it with a remark about what was observed in the past.
So I conclude, that he didn't think about it before asking, and didn't make up his mind, what his question is about, and he invested nearly no work, to improve the question, to clarify what he thinks.
It is just a fun question, which no answer can satisfy. Distinct populations are history - you won't find distinct races, and distinctions you can make are simplifications, where you can't find a serious, scientific paper for.
I feel ashamed about the question, and wouldn't like to see my friends, that such a question is asked here, unquestioned. I think there is a strong smell in the question, and the amount of work, spend to heal it, isn't worth keeping it.
