Back at the beginning of the year, a group of Fundamentalist Christians started a Facebook group called we can find 1,000,000 people who don't believe in Evolution befor June And, yes, the typo is really in the name.
Shortly afterwards, some people started a rival group called We can find 1,000,000 people who DO believe in Evolution before June.
At this writing, the anti-Evolution group has 37,485 fans. The pro-Evolution group has 164,000 (exactly!) despite having had a later start.
The size of the gap is quite surprising. Surveys seem to continue to show belief in Evolution to be losing group with young people, nor is Facebook a particularly tech-savvy venue.
