I may have a bad habit of engaging, but if they post something clearly wrong I like to provide context as to why.

It's not likely going to change their mind, but it's for the benefit of other people. If someone is scrolling the comments of the post, it's possible that they're on the fence or unsure about whatever bigotry is being talked about. I figure if I can help one stranger see both sides of the argument, I can stop the "radicalization" that many of these trolls are going for.

But maybe that's just naive wishful thinking on my part. I certainly don't use social media with the traditional "classic" slur spamming trolls though.
