From my experiences in South East Asia, Europe, and the USA there are more women than men. There may well be differences in the ratio in other places but that's not my experience anywhere I've travelled.From what I've read, this is more a phenomenon in the US church, and perhaps in the West as a whole. In other parts of the globe, men are a greater percentage of the practicing population.
That's not an argument in his favor, it's just not necessarily a universal truism.
