For what it's worth, when I wrote "progressive causes" in my original comment, I wasn't refer to things as black and white as the science on GMOs. I was referring to scientists using their scientific authority to make progressive claims on issues like abortion, or taxation, or anything else that ignores either (a) actual scientific evidence to the contrary or (b) the lack of scientific consensus on the issue at all.

For example, there is significant disagreement within economics on, say, minimum wage. It would be an abuse of authority for an economist (for example, Paul Krugman) to claim we ought to raise the minimum wage because there is an economic consensus that we should do so, when in fact there is not and the said economist wants to raise minimum wage because it's a progressive cause.

A good example of this in practice is Neil deGrasse Tyson's "Rationalia" tweet[0] in response to the Brexit vote. He claims that a constitution should have just one line: "All policy shall be based on the weight of evidence". He is implicitly appealing to authority by invoking the scientific method, and as a progressive he clearly is under the impression that such a technocracy would come to nearly exclusively progressive conclusions. But of course this denies the fundamental truth that he could find a perfectly rational opponent for any of the causes he supports, from public funding of science to Britain's membership in the EU.

The problem here isn't that scientists can be wrong: everyone knows that. The issue is that claims like these are becoming more and more common, and their gross effect is that the very institution of science has become tainted with progressive bias.
