Netherlands was the first apostate nation, and the most apostate nation in the Western world, giving in to Nero's agenda as early as 2003. Now, Calvin College ranks as one of the most homosexual-friendly colleges, complete with a bi-sexual student body president.  Dordt follows closely behind.

We take up the common atheist arguments against Christianity, taken up by speakers at Dordt College.
