Yes, he's a short. The giveaway is the endless negativity. Investors who have lost and become disgusted with the stock have long left, and don't have the time to comment. Those who are still invested don't rag on the company, they hope the science proves valid, and simply want the best for the company and its investors and the patients involved. His motivation is to spring loose a few more shorts to gobble up. And believe it or not, the shorts really do want the shares. Even though reading their comments one would think only a mental case would want the shares.
I tend to agree but there are degrees of offshoreness, so to speak. Israel for instance might want to allow a promising treatment on a non-guarantee basis. No individual doctor would want to sponsor innovative but unproven treatment, but a national health service might.
Many years ago when I was a student at the U of Minnesota, Noam Chomsky was a visiting professor. He held a lecture and invited questions. I recall I stood up in a sea of leftists and asked what he thought of our porous border. I said exactly that...years before the phrase entered common discourse. I am rather proud of that.
His response was that the USA would not have problems with immigration from Central America/ Mexico if we had not intervened in their history many years before ( invasions on behalf of United Fruit etc. ). That was it. It is clear the leftists think no further than the reach of their emotional need to hate the US; perhaps they might spare a moment or two of their time to think of the well being of their fellow citizens - like those near the southern border - but frankly I doubt it.
The disaffection of the American left is something to behold. Ultimately it is limited because there are no more strictly Communist countries anymore, excluding North Korea, and Cuba.
Their movement is running on fumes.
As to what precisely the millions of semi-literate disease ridden Central Americans / Mexican are going to do in the USA is not discussed. They certainly are not going to do any high tech work. They are not going to displace any Indians or Chinese immigrants. The one thing they are not going to do is go back to countries run by people like them. In the meantime they will hate the country that is feeding and housing them.
