A few years back I was a moderator for a large Atheism community (like a FB Group) on the now defunct Google Plus. On one occasion I stood up to some individuals who appeared to be trolling.
For context, the original troll was bashing “Social Justice Warriors”, and I had cause to think this person was trolling other than the options he was expressing. The point of this story isn’t about “Social Justice” or to support it, but rather on how to deal with persons being intentionally obnoxious. The specifics are my hazy recollection, and don’t really matter.
At some point the original Troll called in his buddies to help, but they were all very much the same, so I refer to any of them as “Troll”. The discussion went something like this:
Troll:“SJW’s are bad.”
Me: “I don’t see there is anything inherently wrong with working to promote Social Justice.”
Troll: “Ha! You must be a SJW too!”
Me: "But why am I a SJW? You don’t know anything about me. All I did was try to ask why Social Justice is bad.
Troll: “Women have reached income equality with men.”
Me: “I’m pretty sure that isn’t universally true, and even if it were, what’s wrong with supporting income equality between men and women?”
Troll: “SJW’s are using ‘reprehensible’ tactics.”
Me: "That may be true for some of them, and I do not support reprehensible tactics. I don’t think everyone supporting Social Justice uses these tactics. I do see that there are really issues of Social Justice that need to be addressed.
Troll: “You really are a SJW, aren’t you?”
Me: “Again, what part of this makes me a SJW, and why is it bad to support equality?”
Troll: “I can’t say why, I just know you are.”
[Note: Someone really said that to me.]
This discussion went along the same lines for some time, with different trolls swapping out. Each time I responded by calmly asking for reasons and justification, and not taking any bait offered. Troll could never justify his own argument, and eventually wandered off. I never once resorted to my moderator authority to end the topic, in part because I didn’t want to give them the satisfaction.
My point here is that when a person is being deliberately objectionable, instead of arguing, it may be better to ask them to explain themselves. They probably can’t justify their own claims, and turning their own words against them is far more effective than trying to counter them point-for-point. A point-for-point argument is exactly the response they are hoping to get, and they become frustrated when you refuse to give it to them.
