The discussion happening in this thread does not support your conclusions. As per the HN guidelines:

> Most stories about politics, or crime, or sports, unless they're evidence of some interesting new phenomenon. Videos of pratfalls or disasters, or cute animal pictures. If they'd cover it on TV news, it's probably off-topic.

There is an interesting phenomenon here -- that sex rates are apparently changing very significantly. Whether or not you personally were inspired the post, it is clear that this has provoked plenty of intellectually stimulating discussion here. If the flag button is abused, it makes the moderator's jobs harder. To properly flag posts, a good rule of thumb is to ask these questions before flagging a post:

  1. Are people having civil discussions and learning new 
     points of view in a constructive manner?
     Whether or not you are interested or able to 
     participate in the discussions has no bearing on the 
     answer to this question.
  2. If the post isn't about computers/technology,
     is there something academic about the post?
     Is there data to discuss, its implications, etc.?

If you can answer "yes" to these questions, you probably shouldn't be flagging the post.

I can state that this topic is quite interesting to me. I can also understand why women tend to feel dehumanized by it. But we as a society must not turn blind eye towards problems that afflict humanity. Withdrawing from painful reality won't do anything to address it.
