OK I like this: hat planets.Trek's aliens typically are a "planet of hats." Almost every alien species the crew encounters is shown to have exalted an aspect of human culture to such a degree that they've surrounded it with ritualism and religion to the point of being absurd.
The idea that religion doesn't make sense in a logical Vulcan society sidesteps the fact that if you think about it too hard the logic of Vulcan philosophy starts to fall apart. Is it logical to deny your own nature and emotions? Control, yes. Try to suppress them and act like they don't or shouldn't exist? No.
Good
