There are various polarizing opinions concerning politics and also many different social circles that may have different approaches to certain customs or beliefs.
If the discussions are focused around enhancing one’s spiritual life and creating a supportive relationship environment, then it can be easy to stir away from controversial socio-political ideas.
Even within our Vaishnava community there are different opinions on marriage, economics, spiritual organizations and so on and so forth.
Keep the discussions upbeat and pay attention to those who are sharing. Sometimes people just need to be listened to and that is the greatest demonstration of care.
