Put simply, the above members are not ridiculing a person
That's why social media is so poisonous. People forget that there's a real person that's the target of their comments. No, it's not just some made-up name you can metaphorically kick the shit out of without consequences.
Yet, in a scientific or engineering discussions, we need honest feedback, and yes, even ridicule where ridicule is due: otherwise, we accept anything non-shit as perfect.
But the target is, and must be, always, our output –– even when talking face-to-face. The output can be modulated, controlled, adjusted; our person cannot. So, the desired change in attitude is to make sure that the focus of the ridicule is not the person, but the output.
("What you are saying is nuts", instead of "You're nuts". I know I fail in this too; my only defense is that I was about forty when I learned this: somewhat stuck in my habits. It is difficult to drop a habit that is repeated all around you, but at least I know it is something I want and need to work on.)
What I didn't like, is labeling OP "conspiracy theorist", because it is one of the labels used to mean "hey everyone, you need to ignore the output of this person; not because of the output, but because the person apparently belongs to this category". It is one of the terms that imply something completely different to what it actually means, just like "emotional intelligence", and a perfect example of strong tribalism even among science/engineering types in Western societies.
I am a conspiracy theorist. I do not believe in basically any of them, but I like to entertain them in order to understand the reasoning among those who do, and also because I find it fun to try and extrapolate the real world effects if it were true. I like reading about new conspiracy theories. I also like to read about new scientific theories and models, although I do not even consider their applicability/reliability until they are used to model or predict something physical. So, I am also a fringe theory aficionado. I don't mind entertaining things that have a very low probability of being useful/correct, as long as there is something related to that thing that I can learn that is; and usually, that thing is about the people who believe or discuss such things.
The difficulty, as in this thread, is when an OP is not interested in honest, critical feedback, but is seeking
support.
Now, that
support, is exactly why you get sub-reddits and whatnot where all sorts of inanity is amplified. Having observed some for a few years now, I do not think they actually believe in most of what they apparently agree with, as they are really there for the support and not critical or intellectual discourse. To feel not-alone, instead of actually examining their thoughts and ideas.
In other words, because of emotional reasons, and not for any kind of intellectual pursuits.
The human world is the kind of world where a good
brand is worth more than any product.
