Rewrite needed[edit source]
I've already rewritten a badly-written sentence, and removed the "Trivia" section as the latter added nothing that hadn't already been said in the article.
However, there still remains this sentence:
I don't know what this is supposed to mean, or I would have rewritten it to be more grammatical. "Between their customs" and what other factor, precisely? As written, this sentence doesn't make sense.
