A thought, something you’ve read perhaps, might seem very profound. You may have an “A-ha!” or “Eureka” moment, whatever you want to call it, perhaps just a simple “moment of clarity.” You go to your favorite social website to expound upon your newly found knowledge only to have someone “BTDT” you or perhaps quote some 16th century philosopher who said the exact same thing long ago. Your epiphany is just that, your epiphany. It's profound based on your own personal experience. It’s likely that those jaded “BTDT” types thought it was an epiphany the first time they came across it too, despite their cavalier attitude toward it now.
Religious unity really isn't such a strange idea. People have been uniting through religion but also uniting different religions together, at least the parts that fit for them. To be clear, it more often isn’t the idea of it that might seem strange, it's the implementation. Look at religion, I have heard many people claim that they believe in unity, there is even a religion where congregants refer to themselves as Unitarian but mostly, it isn’t so. In many cases they say, “We will accept you unconditionally” when what they mean is, “We will accept you unconditionally so long as you are like us or are willing to become like us.”
