I don't think it's unreasonable to think that someone could look further into something, be called to something (or however you would phrase it) from a starting point of 'cool'. The possibility is there at least, I would think 🤔

Truth, beauty, and goodness are, at the most fundamental level, the same thing. There is nothing wrong with being drawn to some good by an aesthetic sense, for aesthetics are a clue to the truth and goodness of a thing.
Someone who is drawn to religion because it's "cool" will, if he or she is genuinely seeking, come to engage with it on a deeper level in time.
Wonderfully put:)
