So in other words it is better to not even try and sit with a smug face and smartass comments instead. 
I wouldn't be doing it if I didn't believe it 
On one hand a guy who has been using mercury for years and is still alive, on the other hand a guy who says that by his logic the other guy should be dead. Who wins?
I guess you don't understand that "handling mercury" and "soldering with it" (= heating it up, producing clouds of toxic fumes and splatter) is not quite the same thing. Also mercury won't kill you outright - you know, it used to be used as a remedy for syphilis, typhoid fever or parasites (yes, you were literally asked to drink it, if the patient died, oops, clearly that parasite was too strong and mercury dose too small!). The problem is long term exposure - the dose is cumulative, mercury accumulates in your body over time (same as lead and cadmium).
That the guy isn't dead yet means squat - the video has been posted on 25th of October, he claims it is a "new method", so it is very likely he isn't doing this for a sufficiently long time to have accumulated enough dose to have serious problems yet.
You are only showing your ignorance, dude.
And if Indians or whoever consider mercury a medicine then guess what, kicking them out of YT will at best push them to some Indian site where no one will see anything weird in it.
I don't understand people who get emotional about shit they find on the Internet. 
So in other words, it is better to not do anything and let clueless idiots get hurt/poisoned, even though we can at least alert YT about it. I can't do squat about any Indian websites but that doesn't mean we should ignore shit like this where we can do something about it.
Wonderful attitude - are you also that guy who, when seeing a road accident, whips up the phone and starts filming instead of trying to help, because "it won't make any difference anyway"?
