How do you think we'll achieve that, Adrian? By carrying on at this steady rate or some explosion of interest from the atheist community? Without a huge movement (huger than what we have now at least) I can't see any real progress being made in that time limit. In England maybe, but not in the states. Atheists are probably at war with too many different groups and ideologies to get far in politics. We're split between the anti-creationist enthusiasts, the LGBT enthusiasts, the pro-choice types, the separation of church and state people, those who are fighting against "one nation under God" and "In God we trust", those who are fighting theistic claims only... etc o.o
Obviously there is a lot of overlap and many atheists are taking part in many of these causes together, but unless some sort of common group or idea is established, we'll be a minority split between twenty battles. We all have our own pet projects to pursue. Herding cats is indeed a valid description

I said 55 years The new atheist movement is really quite new (been quickly buiilding up over the last 8 years) so give it a few decades and I reckon we'll see some progress.
