Chris, while I don't condemn what you are doing - good on you for your passion regarding this, but these poeple thrive on interventions by you and others. They are given a voice because of your contradiction to their outrageous claims. I feel that the best way to deal with them is to ignore them. Surely those of us with the knowledge of aircraft are able to flesh out the wheat from the chaff, so in my opinion it's best to just ignore them and back away on social media. Correct their rubbish if you must, but don't indulge them. Maybe it's my distrust of common forms of social media, facebook, twitter etc, as opposed to the likes of specialised aviation forums like this, that lead me to take this line - I don't go on common social media at all. When idiots come on to specialised forums like this, they are quickly exposed for what they are, thanks to you guys as mods and us as knowledgeable and well intending attendees.
