Atheists don’t boast superiority nor they profess of being the enlightened one and Religion plays little to no role in determining superiority nor does it affects enlightenment.
Superiority is a simply a concept made-up by narcissists with a god complex. Superiority doesn’t imply enlightenment not does enlightenment imply superiority, men are not created equal they “were” equal. It’s the inner moral compass that guides you to enlightenment, not your religion or the lack of it.
History has numerous examples where men claimed they were superior to others because of their religious beliefs or the superiority of their religion. But just look, what these superiors have done. From the ulama’s of Islam, who use jihad as a tool to commit murders in the name of God; to the protectors of the faith of the Christ with their of crusades and franchise of conversion; or the god-men of Hinduism with their megalomaniac egos. These over glorified fascist and fanatics have twisted and drained the entirety of Morales and aura of enlightenment from their own faiths.
Just because, you have a different belief system which you consider to be an epitome of enlightenment or a social order that you remark as civilized, doesn’t necessarily makes you superior or enlightened.
Think about it, the Spanish conquistadores present them themselves as gods to the Mayans and Incas, proclaiming to be enlightened and superior to their ancient ways. But these enlightened supremacists destroyed a much superior society. I agree they were barbarians but shouldn’t these enlightened gods have instead helped them overcome that one thing. Or weren’t these enlightened beings as barbaric as them, for slaughtering millions in the name of God.
In fact, modern educated society is also not different in that regard. Men like Jim Jones, Shoko Asahara, Bhindranwale, Joseph Koney, Abu Bakr al-Baghdadi and much more developed a cult around them which ultimately leads to the death of humanity itself. Hitler professed of Aryan supremacy and look what he did with that supremacy. And only an egomaniac narcissist would think that some people are superior to others. Africans were said to be an inferior race but science ultimately proved that in fact, they are the real forefathers of humans race on earth.
So you see enlightenment and superiority are worlds apart. An enlightened society will never deal with a relative concept like superiority.
Buddha was enlightened but we turned him into a religious figure and polluted his teachings. Krishan was enlightened but he is was promoted to the status of a god, Christ was enlightened and still, millions were slaughtered for his glory, Mohammad was enlightened but we killed his ideology for a ransom called heaven.
