But you can't go into depth very far on any of these without reaching political topics, can you?
Our culture has become a toxic stew caused by everyone forgetting to mind their own business; partially because people think that because politics does have a part of everything people do (hence the etymology of the term), that it gives them the right to control others. Fascism is the end result.
Completely agreed on that point. In fact that's how politics should be discussed.
But if we consider politics to be "what should we do as a society?" then you can't avoid political discussions in those topics still, right? You can only seek to discuss such topics tolerantly and maturely, I think.
