Honestly, converts and the newly religious are their own worst enemy.
From knowing nothing, suddenly you know it all. Yesterday you did not believe, but today you are the truest believers of all: yours is the saved sect, free from error and misguidance, purified of the heresies that disable all other believers everywhere. It is time to publish a hundred books, to establish a dawah website, a YouTube channel and that persistent social media presence. All of a sudden it is time to teach, and to guide, and to lead others into the light.
