What place does civil discourse play in a democracy?

This question is in the General Section.

Wikipedia says: Civil discourse refers to respectful conversation aimed at fostering understanding and constructive communication, where individuals within a group share different perspectives, enhancing the learning experience.

I grew up in a time and place where people discussed events with an aim to air ideas. Most hoped to persuade, but it wasn’t always the intention.

With the rise of the Religious Right in the 1980s, the idea that one side is correct and ordained by God has meant less discussion and more strident preaching at opponents.

Since the 2016 election, the radical left can sometimes appear just as stubborn and deaf to civil discourse.

What part does civil discourse play in your ways of discussing current events and topics of importance? Do you aim to hear and consider opposing views? What intentions do you hold when you speak? What’s your aim or motive?

Personally, if I sense I will be heard respectfully, I’m eager to voice my thoughts. That is rare these days, and almost nonexistent on the internet where we can each hide behind our screens and ignore the humanity on the other side of the interaction.

Can we keep this thread civil?
