You mentioned that you have changed you views about certain topics in the past.
If you have some specific topics for which you remember the crucial turning point - whether it was some event that happened, something you discovered, or something you were told - it would be interesting to hear. Such turning points often come with interesting stories, and we might learn something as well from them.
Of course, changes of opinions can come gradually, but even then we sometimes have some moments that were more significant and remember aferwards.
