I, for one, support the progression of mankind. Having said that, I feel that religion is indeed the "opium of the masses" and only acts as an anchor that hinders the progress of mankind. Of course, some religions aren't as much of an anchor as, say, the three main monotheistic religions.
Many people are just find without religion, but there are some people who need the hope, albeit false hope, that religion can offer. I don't need that hope, and likely never will. To be honest, the Jecultah's Blindness religion has made me hate religion as a whole, although I appreciate the culture and traditions of religions, like the architecture of Orthodox churches or the Hajj to Mecca.
