I have a soft spot for the topic of people who are dual faith. It’s weird, you know. If you’re an atheist, you get a thumbs up from me. If you’re religious with one faith, you get a raised eyebrow from me. And if you are dual faith, you get two thumbs up from me. It just feels like you’re more open-minded if you are more than one faith.

I like Japan’s “whatever” attitude to religion. Like it’s just there and you can play around with it if you’re bored.
