How about, instead of trashing theories or ideologies you fear, you offer evidence that would contradict statements you disagree with? Your 'refutation' contains no factual evidence to contradict the original statement. Do you believe that children do not play non-competitive games in any culture, or just not in Semai culture? Or that non-competitive games do not or cannot exist? Or that it's unlikely or impossible that Semai children would play only non-competitive games? When you say that an author of an article in this encyclopedia ought to "present all sides of the story," were there particular other pieces of information or other theories that you thought should be presented?
