You are in good company here on HN but in general this is not how people work. Specifically re religion and politics, the reason it is a common adage to not discuss them in social settings is because people rarely engage rationally in those topics. For whatever reason, it triggers people's emotional reactions deeply and quickly. When people's emotions are involved rational discussion departs quickly, and (positive, negative) feelings linger.
This to me is destroying social debate. How can one grow without believes being challenged? - I don't want to live in my bubble of self-confirmation. I want my believes to be challenged with good arguments and improve my thinking.
Of course the key is "good argument" and not "bah stupid"
