(arguing about whether the US was founded on Christianity - he was asked to present evidence)

He'll acquiesce he says! TO UNDENIABLE ESTABLISHED HISTORY!

No worries, loather of truth that flies in the face of your nasty little revisionist version of history. You are not required to acquiesce.
In fact, your posts serve a very important purpose here at the Christian News. They reveal just how desperate, dishonest, and devious the liberal left is to distort known facts to further their disgraceful agenda.

Keep up the good work!
