I like how the RE perspective is to just look at it from their own closed view of the world.
If FET is true, it is not dangerous. In that case RET should be the one that gets all the scorn you heap onto FET.
Mainstream science has become a cult, much like political discourse. You must agree with A, B and C to fit in; politically it's even more nonsensical, there's no reason topics like healthcare and homosexuality should be even remotely correllated and yet huge swathes of people are expected to only believe the same thing about one if they think the same about the other, and magically somehow they do! Borderline brainwashing. You get told to fit into a specific political model, left or right, Republican or Democrat, Labour or Tory (US-UK dual citizen here) so you end up doing just that even when all the disparate things surrounding you should not be connected.
Scientifically it's the same. You are taught what people believe, not how it was developed, not why it is believed; not for years on at least, by which point it's nicely ingrained.
But, just for fun, let's take a step back and look at it from a neutral perspective. No, forget that, let's look at it from your perspective, let's look at it from the FET-is-all-rubbish-and-wrong point of view.
What then? What is FET? It's people who are mistaken about something, and who go out... and try to work things out for themselves. Look at this society. It is open minded, it accepts different models and points of view. Yes it gives suggestions, what people have learned before, but it doesn't yoke you to them. One of the strengths of FET is open-mindedness. The FES tells us to go ahead and think for ourselves, a far cry from all the paranoid comparisons you're drawing.
It doesn't tell people to gout out and hurt each other, it doesn't tell people to start risking their lives or doing anything close.
And that's what sums it up, really. The danger is not FET, the danger is cults. Sure there are people like Dubay who want people to blindly follow him and to connect disparate threads, much like modern political parties, but he's one voice out of many. Someone interested in FET is going to google it and find a whole wealth of content to explore, multiple youtube channels discussing multiple models, and then this forum happily telling them to take their time, to see what works.
FET tells us to think for ourselves, not to blindly follow, and it is blindly following that has gotten the world into the mess it now is.
