No. They are being phased out (at least in the U.S) because people aren't buying them, and have been swept up in the glamour-world of hybrids and BEVs.
And, if you think that diesel-fumes are deadly, just try accidentally touching the wrong connection in one of those hybrids or BEVs.

So? 
So is breathing gas-fumes while refueling. So is getting engine oil on your hands if you are changing your own oil. So is the gaseous-vaporization from some of the materials used inside vehicles for upholstery and trim. Do are dozens of other materials in and around the typical vehicle...and your home. If one does not want to be exposed to anything harmful (or potentially harmful, the best thing to do is not to get out of bed in the morning...and, even then, the very air inside your bedroom could have Radon gas.

Let's see, petrol vapours are controlled by all manner of systems from the production to the gas gas pump to complicated hardware in your car. If you change your oil with bare hands you're an idiot. We as a society generally do all we can to eliminate or at least reduce harmful compounds. Justifying one form of toxin because another exists is silly to put it kindly.

Well, that's one reason WHY the public isn't buying diesels (besides VW's cheating). Propaganda, unfortunately, sometimes works. They have been sold a bunch of nonsense that diesels of today are bad for them, and are destroying the environment.

The public doesnt know anything about VW's cheating. Diesels just dont make sense in America, the costs are too high, they have a stigma in America, theres just really no reason to buy one. They do well in Europe for economical reasons.

Maybe they have forgotten by now, but one cannot say that they didn't know anything. It was front-page news in many major publications.....even non-automotive ones.
I also wouldn't be too quick to accuse the public of "forgetting" things too soon when you still have people (and, yes, I still occasionally see them or deal with them) that, even today, won't go anywhere near a Korean dealership because of what they were building 30 years ago LOL.
The trouble-plagued VW diesels of the 70s/80s, and (especially) the simply-awful 5.7L GM V8 diesel (which, along with the Corvair's oil-splattering air-cooled flat-six, was one of the worst power-plants the corporation ever came up with), is what really turned the public off to automotive diesels. Mercedes and Peugeot, however, even back then, proved that durable/reliable automotive diesels could be had, although, in Peugeot's case, that reliability did not extend to the rest of the vehicle...that's what drove them to of the U.S. market.

Lets put it this way, *I* barely remember. I just asked my wife about it and she had no idea what I was talking about. People just don't care about cars the way we do.

Not only that, but, she probably doesn't have the time to discuss it that you and I do LOL. Raising two kids that age can take up lot of a mother's time....assuming that you don't have a maid or Nanny.

When I was in college getting my mechanical engineering degree, I took a class that was all about engines. At that time (mid to late 90s), diesel engines were much more efficient than regular gas. Diesels were hitting around 42% thermal efficiency if I remember right, and gasoline was in the ballpark of 24% at that time. There are now gasoline engines hitting over 40% that can get the same gas mileage as diesels, no to mention what hybrids can do. Diesel passenger cars just don't make the compelling case that they once did. You still have the diesel maintenance and limited gas stations, but they don't stand out above their gasoline counterparts in fuel consumption like they used to. It's a tough sell.

Car & Driver, in a very recent article, still gives the edge to diesels in many driving-sutuations. So does autocar in Britain.
