That's a terrible analogy. You know maybe if we lived in a world where the overwhelming majority of people weren't religious it might be stupid. But it isn't because we do live in a world/ country where your religiosity is assumed and you're looked at weirdly for not being apart of the in group. Where you might not get jobs or contracts if people found out. Where a lot of people wouldn't date you because of the one single reason. If you lived in a world where liking blue was frowned upon you might go to a festival celebrating it. Hell that sounds like something that might already exist.
