No, it is not. We are an evolving specie. It may be that we create a different society in another 3,000 years, it may not. We have recently enjoyed outgrowths, tendrils of societies that are fully engaged and simultaneously creating peaceful links where people who desire to do so emigrage to other cultures. The biggest contrainsts, cultural differences in small geographic areas, may then be moot, as people will no longer force oppression on others, whether that is Sharia or tollerance.
