There is no shame in that, given that it is well defined. For instance. In almost all sports you have a male and a female devision. Just based on pure strength or something. Call it what you want. There ARE differences in various humans. Some are male, some are female, some have kids, some don't, some have two legs, some don't, etc. Want to give them all equal chances? Listen to what they can and experience and get them to listen to each other for mutual respect.
