Things you shouldn't have to agree to disagree about
An all-powerful God cannot exist.
If an entity was all powerful, it would both be able to create a rock so heavy that it couldn't lift it, and also be able to lift it. As these two things cannot be possible simultaneously, an all powerful entity cannot exist - and so an all powerful God cannot exist.
The smartest men are smarter than the smartest women.
There is an overwhelming amount of evidence for this.
The current scientific consensus suggests that while there is no significant gender difference in terms of averages for most quantitive measures for intelligence, there is a greater male variability.
This greater male variability suggests that there are a larger proportion of males at the extremes - both at the bottom end and the top end; which further implies that the smartest men are smarter than the smartest women.
As a potential case study, 121 chess players have achieved an ELO rating of 2700 or more. Only one of those was female, Judit Polgár. If we assume that each of these 121 players had an equal chance of being male or female, then the likelihood of this happening would be 0.0000000000000000000000000000000005%.
