This is a story about how someone from the Westboro Baptist Church left because of the way that people engaged with her. https://www.youtube.com/watch?v=bVV2Zk88beY
What's worth noting from this story, people that were hostile in their interactions with her only served to entrench her further in her ideals.
What caused her to change her mind were the people that had "friendly arguments" and made an effort to learn where she was coming from.
She listed out 4 key points when engaging in difficult conversations. I extracted/paraphrased some of what she said below:
Don't assume bad intent (assume good or neutral intent instead) - Assuming ill motive almost instantly cuts you off from truly understanding why someone does and believes as they do. We forget that they're a human being with a lifetime of experience that shaped their mind and we get stuck on that first wave of anger and the conversation has a very hard time ever moving beyond it.
Ask Questions - Asking questions helps us map the disconnect. We can't present effective arguments if we don't understand where the other side is coming from.
Stay calm - She thought that "[her] rightness justified [her] rudeness". When things get too hostile during a conversation, tell a joke, recommend a book, change the subject, or excuse yourself from the conversation. The discussion isn't over, but pause it for a time to let tensions dissapate.
Make the argument - One side effect of having strong beliefs is that we sometimes assume that the value of our position is, or should be, obvious and self-evident. That we shouldn't have to defend our positions because they're so clearly right and good. If it were that simple, we would all see things the same way.
You can't expect others to spontaneously change their minds. If we want change, we have to make the case for it.
I'm not very musically inclined, so I have no idea if this is B-flat minor or not, but what you described kind of sounds like "Jazz in Paris": https://www.youtube.com/watch?v=mNLJMTRvyj8
It's one of the songs that you can select from Google Photos when making a highlight video.
