scorpion, my brain works just like yours, but my feelings have a mind of their own.
That's what I tried to describe.
No, that's not quite correct. It's just that I don't have this black-or-white view of it. I don't take those videos as proof, but I wouldn't call them untrue either. They're more like diaries to me, but in summary they make the pendulum swing towards the direction of "true".
The fact that stenosis, treatment, re-stenosis and re-treatment has such straight effects to symptoms cynically makes the placebo effect very unlikely. Unlikely, not impossible. Another push in the same direction for the pendulum.
The fact that there's a growing number of phycisians looking into it and the fact that there's a huge history of studies that link MS to a vascular etiology are two other pushes. There are some more.
I totally respect that none of these explanations satisfy you (or any sceptic). I wouldn't say (yet) that the CCSVI hypothesis is true. But I haven't seen any argument against it that convinced me, but many that at least pointed in one direction.
Science isn't about finding out what's true. It's about finding out what's not wrong. Yes, there's a difference.
But I don't want to convince you of anything. To me, your point of view is as good as mine.
