Lefty professors ask a loaded question rigged to produce the result they wanted, anyone suprised? Good way to prove our point that science has been politicised to the point a lot of us take a default position of "BS!" on any pronouncement from the white labcoat set that has the slightest whiff of politics.
We notice that all of the mentioned 'science' issues are tied to public policy positions of the left and that the 'scientists' are working outside their areas of expertise when they push policy solutions to the problems they 'find.'
We doubt AGW because we have been given very solid fact based reasons to. We see hacks like Mann protected from the consequences of his fraud with the 'Hockey Stick" and nay, even rewarded for it. Cleared from all wrongdoing by the same corrupt institution that turned a blind eye to Sandusky and covered his crimes until they exploded into the newspapers. And both for the exact same reason, they were stars who brought in the sweet sweet cash money.
The whole HIV/AIDS thing got wierd because it is a complex and murky thing and yet anyone with an eye willing to open it could see that it was totally politicized. It was the only disease in human history to get a bizarre sort of 'rights' attached to it. Whole lines of research were simply forbidden as career ending. Consipracy theories almost always pop up in vacumns of fact, especially when it is pretty obvious that facts are suspected but being supressed.
