Let’s set some ground rules.
Etiquette for any discussion: Indeed, Islam has given us the key to everything, including how to hold a beneficial conversation. And that’s what you should aim to have. Debates are a waste of time and energy if they are setup for the participants to fail. I️.e. both people engaged in the conversation refuse to be open minded or hear each other out.
So even if you believe you know the answers, make sure to listen to all the points being made.
Let them feel you’re being receptive and working towards the common goal of understanding and applying the deen to the best of your ability.
