Paine is remembered very well. When I was in elementary school in the 70s, we were still learning about "Common Sense" and the role of pamphlets in the Revolutionary period.
In Morristown, NJ there is a monument commemorating Thomas Paine.
I do agree with the author that Paine's anti-Christian writings were out of step with his peers.
Where in Morristown? I've never seen it.
