Ideally, it shouldn't make a difference what a person's gender, race, ethnicity, sexual orientation, religion, etc. are.  We'd just see and accept people for what they are.  Y'know where you see this the most?  The kids in daycare.  

Ironically, the government seems to think the best way to achieve this is through identity politics, which emphasize differences.  "Acceptance of diversity" is a lot like minor hockey....the kids seem to get it quite naturally, but it's the adults that tend to ruin it.
