Oddly you probably get the most understanding from me. I get being certain, and that certainty, while being unusual, isn’t actually terribly interesting to talk about. At least in your case, your certainty leads to interesting follow-on questions, though 😉

That said, we should all be careful not to interpret other people’s descriptions of their own faith, or lack thereof, as an attempt to convert others to their point of view. There is valuable stuff to learn from other people’s religious viewpoints, whether you agree with them or not.
