Was there ever a time before RedCream? My theory is that there was NOT.
In fact, my Gilgamesh series of arguments -- where I decimated all the religifags by proving their gods don't exist -- was a classic moment in 4channery.
I suspect that a lot of /sci/ regulars were so offended at being shown their gods don't exist, that they took off for friendlier climes for their religitardery. No loss to /sci/, for sure.
