That's right. The only difference lies in biology. The rest of the differences are created and forced by society with stereotypes. Because of this, many people believe women can't be as strong or adept as men in hand to hand combat, or they can't be as tough as men. This isn't true, so it may not count unless you think that because people widely believe in this crap, it makes a "difference". [ The last part is said with a slightly mocking tone towards those that do think it's a difference. ]
