I usually start by assuming good faith, and there was a time when I thought it was useful to engage pretty much anyone in discussion, even if the chance of anyone changing their mind was low. This was particularly the case in the days when the old SSSF had a goodly number of random visitors and first-timers etc, because I wanted to make what little contribution I could in the battle against pseudoscience.
I’ve had considerable dealings with one of our contributors, and after several years I can more or less predict how things will go if I seriously engage him or her on his or her terms.
The person will post pseudoscientific views on climate, either out of the blue or in response to an actual news item based on the work of climatologists. I’ll take a bit of time to refute the points one by one, using relevant journal articles. The person will reply with articles from a pseudoscientific website hosted by someone without scientific credentials. I’ll take a bit more time, disproving the data or showing the flaw in the logic.
Next, the person will shift the goalposts, or change the topic completely, and I’ll go back and do it again. The next day they’ll show up seemingly having absorbed no information at all and just post the exact same nonsense as before.
Recently, I’ve stopped engaging this person. Perhaps in my maturity I value my time more. Perhaps, because we don’t get random visitors here anymore, I’m not so worried about anyone else being taken in by pseudoscience. But I’m not edified by the above process, and certainly the other person doesn’t seem to be learning anything, so there’s really no point. Instead I’ll just post articles on climatology and discuss the topic with any of the various non-trolls.
