It would take several columns to parse that statement alone, but just look at the misleading phraseology: "The majority of Americans … have come to a consensus." Assuming a majority favors embryonic stem cell research -- and even federal taxpayer funding for it -- is it not deceptive to imply that a majority constitutes a consensus?

Of course, those who agree on a proposition always share a consensus among themselves, but doesn't "consensus" suggest that there is almost unanimity on the issue?

The answer is yes. The Obama left repeatedly uses this type of language to manufacture the impression that only a fringe minority disagrees with the overwhelmingly accepted majority view. They declare a consensus when there isn't one and bully the true opposition from voicing their concerns. They do it with global warming, embryonic stem cell research, "intelligent design" theory and now Keynesian economics.

They have plenty of help from the liberal lapdog media. They dutifully report that Obama is lifting a ban on embryonic stem cell research when there has been no ban on such research, only a restriction on federal funding for it. Nowhere do they acknowledge the genuine ethical objections to or the scientific problems that have been encountered in such research. Instead, they just portray opponents of federal subsidies for the practice as Luddites.

While the left ridicules those who don't buy into their decreed "consensuses," they are the ones who suppress scientific inquiry and debate on various issues. They are the ones who suppress publication of facts that contradict their agenda.

You'll rarely hear from them about the failures and hazards of embryonic stem cell research, such as a report that embryonic cells injected into a boy caused multiple brain tumors. You'll never hear them speak about the increasing successes of adult stem cell research, even though adult stem cell science is less expensive, more accessible, probably involves less cancer-causing risk, and is not ethically controversial.

Beware; when the Obama left mounts its rhetorical high horse and tells us it is advancing science in furtherance of a consensus, it is most likely signaling that it is implementing a highly controversial, scientifically dubious policy whose opposition it intends to intimidate and silence with the formidable force of the presidential bully pulpit.
