This is incorrect and very puerile (it’s theological slop) and even in a Christian frame this is known as Marcionism which is a heresy.
But it was not meant as two gods, it's meant as the hard god father changed his mind seeing the son die for the humans. I always also think of Trinity - but I'm a bad Christian anyway. So thanks for pointing to Marcionism.
Part of their theology even leaked into the Gospel ( John 1:1-15 ).
But, I don't see any dualism here, only a (baseless) accusation of such by monideas. In the old testament God was hard and cruel and he is much nicer in the new testament. Marcionism is the idea that they're separate gods, which is not what theGeatZhopa claimed.
I wonder what the Christians here think about Dr Ameri? I'm not convinced at all.
Most of us are atheistic with regards to most gods. Some of us just go a little farther...
The point is to convey how Dawkins and his ilk (e.g. deGrasse Tyson) have so many basic fallacies that they do not seem to be aware of the moment they step outside their domains, and try to apply their relatively narrow world view across domains that do not support them. The video talks about a very fundamental logical fallacy.
The topic of the existence of God is not the discussion here.
