I was alive too and moved in sf/fantasy circles. And I am saying that you are just being sexist and wrong.

If you have seen only boys liking Harry Potter, LOTR or Ender Game, then it is purely result of who you picked as friends. Because girls read all of those.

I said girls loved Harry Potter and LOTR. Girls forced me to perform the Harry Potter theme in band class because I was the only one good enough to play it! And its wasn't my friends. It was the entire class.
