Are you willing to reassess your relationships, your elitist Baha'i attitude demonstrated regularly on this forum? If not, then the statement is moot. As many others have said, education that promotes harmony is all around the planet right now. You really think I would have tolerated hate of others when I taught school for 30 years? Here, right now, in high schools there are LGBQT support groups, anti-racist policies, and much more in that regard. This idea of yours is certainly nothing new.
If the world is to move on as you would suggest, we need to drop religions like Baha'i who have doublespeak in their system. If it meant more harmony, would you be able to drop your Baha'i faith in favor of something far more progressive?
