In my opinion, the best advantages rationality can gain is a totally reasonable intelligent well spoken blond woman wearing sleeveless dresses smiling and explaining with devastating clarity just how much sense atheism makes.

Possibly, but...

The reason this makes the mullahs want to spit at her and kill her is because it is a threat to what they are selling, which is precisely why rationalists should keep doing it.

To achieve that all you need is "a [cut] blond woman wearing sleeveless dresses smiling [cut]".
