Rationalists who take religion seriously, for instance.
Take seriously in what sense?
For instance, I spent about six years seriously studying up on religions and theology, because I figured that if there were any sort of supreme being concerned with the actions of humankind, that would be one of the most important facts I could possibly know. So in that sense, I take religion very seriously. But in the sense of believing that any religion has a non-negligible chance of accurately describing reality, I don't take it seriously at all, because I feel that the weight of evidence is overwhelmingly against that being the case.
What sense of "taking religion seriously" are you looking for examples of?
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
