Before the Creationists took over, Darwin's birthday was a public holiday in the United States.
When was that?
The last I time I looked, there was no prayer in public schools, "intelligent design" was taught in very few places, and more and more merchants were banning "Christmas" from their holiday vocabulary.
Those "cunning" creationists...so stealthy in their "takeover" that they actually made it look like religion was being excised from public life.
