JKDS, I don't get your resistance to this and you're being somewhat obtuse, which I find weird. Of course LEGOS or Rubik's Cube or whatever aren't hard-wired into our psychology but as Rilla said, LEGOS represent a class of things that interest boys. In previous generations or centuries, it would have been building blocks and puzzles or what not.

obviously team sports have been around for centuries and probably millennia.

Moreover, the existence of LEGOS and football is proof that something about us makes us like them, because we invented them.

Sexuality/gender is continuum; there are certainly gay men and women who love sports or other "masculine" activities as spectators and participants, but it's hard to take you seriously if you don't think that gay men or women are somewhat wired differently in their interest in these things. I'm guessing that gay men were given footballs and toy soldiers to play with as kids, not Julie Andrews albums.
