I wasn't either. I just noticed him being on the guest list and thought it very odd.
Here’s my train of thought on this...
Well when you think of oranges that reminds you of apples
and then apples reminds you of Newton and
I believe the Newton inference has to do with his literal ‘yec’ worldview
which has been the source of so much consternation to those who deny that was Newton’s viewpoint
[even thou Newton also did add up all the begets and begots
like Ussher did when he calculated about 4,000 years age for all of creation from the old testament that Jesus also studied and affirmed completely in his heyday]
so these neo-Newton folks if you will
along with other folks who simply reject the Bible without ever reading it much
will then rather mindlessly usually switch the debate back to apples and oranges
to keep trying to impress the faithful that one’s worldview
only matters as much as the difference between apples and oranges
But then again maybe not...
