Here are some one liners...
The Act of Uniformity Produces Political Correctness for Religion -- In an attempt to bring Anglican, Puritan and Presbyterians together, the Anglicans create a rift and eject 2,000 clergy from the fold. I talk about the origins of political correctness.
Say Bye-bye to the Dodo Birds... and the Indians -- This year marks the last sighting of the Dodo bird. I talk about how extinction times are calculated and how feral pigs not only destroyed the Dodo bird's food supply but in New England, feral pigs ate the emergency food supply agriculture-based Indians as well. That and other reasons will cause a reduction in the number of Indian tribes that base themselves primarily on agriculture.
