One of my friends recently shared some really helpful advice about engaging in Facebook debate. I can’t share his name as he’s a missionary in a sensitive context, but he’s given me permission to use his material here.
“There are people with whom I disagree but whose posts I always read carefully and appreciate. There are people with whom I agree where I cringe when reading posts. (All of these are people I like, agreeing or disagreeing doesn't change that.)
Most arguments on Facebook are out of frustration and don't actually bring two sides to better understanding. I don't think it's what anyone sets out to do, but we're angry and want to vent.
Whether or not I agree with anything you say, I'll listen if you say it well. So...
Tip #1
It's easier to direct blame when you're angry, but not helpful. Identify the issue clearly before (or even without) assigning blame to a person or group. Keep your focus narrow and avoid tying that issue into a whole network. Even if it is connected, let your readers tug that thread and unravel it themselves. Their own conclusions will be much more convincing to them than being spoon-fed by someone else.
Tip #2
Consider your sources. It's fine (really!) that you read news sources tailored to you, with stories that fit your view of the world. But if you want to present an argument to someone else, check the facts across multiple sources and then offer the sources that you believe will be seen as neutral by the most number of people.
Your facts may be right, but if it comes from EveryoneWhoDisagreesIsAnIdiot.com, you're undermining your own argument from the get go.”
