As simple as possible to summarize the best way you can, first, please. Feel free to expand after, or just say whatever you want lol. Honest question.
I don't think you're correct with your argument. Why would someone choose any particular religion? That's the argument. There is no logical argument for that. There are arguments for choose one in general, although logically very flawed. Still, there's no logical argument I'm aware of to choose a specific one.
