I've never met an adult convert who gave off any other vibe than "I am afraid of grappling with the world as it is, so I am turning to a comforting fantasy." They can and do often dress it up in various fancy phrases. They decry the awfulness of modernity and claim religion is the solution. But it is rhetoric. People don't become religious as adults because they are dumb or lack eloquence. They convert out of fear of the world.
