A theist proposing anything based on their religion is not on any kind of ground at all.
No, that assumes that religion does not have a linguistic and philosophical framework or argument which of course, is crap.
Trueman also points out that Dawkins, apart from any religious consideration, cannot derive his authority to speak on gender and sex from science in the way he thinks he has.
So assuming God the person arguing of a traditional view of gender and sex is arguing consistently
But a person arguing those same traditional views from science is not being consistent.
The difficulty for the Freedom from religion movement is that it made Coyne and Dawkins their authoritative base and are the victims of their own scientism.
