The most conspicuous example, of course, is that of global warming: it
is an article of Democratic faith that global warming is both real and
man-made
If by "article of faith" you mean "provisional conclusion drawn by examination of evidence and in accordance with viable theories whose component elements have been repeatedly and independently verified," then maybe.
I don't know if this is about wanting to be "fair and balanced" or if it's just right wing projection, but the last item I'd list in the vast catalog of Democratic party flaws would be adherence to "left wing" ideology.
The right, of course, makes no apology about their "ideology," having effectively marketed it. But whither Coke without Pepsi to bash, right? So therefore their political opponents must ALSO be driven by ideology. Not, you know, facts or actual results. Heavens no.
There are ideologues everywhere, it's true, but it's ridiculous to claim parity between programs designed to find ways to "fix" gays the vast, overwhelming scientific consensus that global warming is real and man-made.
Praying away the gay is an explicit ideology. "Gay is bad, God said so, therefore it is good and righteous to fix the gay." That's the unapologetic radical straight agenda: turn everybody straight. As an aside, that's where there must, of course, MUST! be a "radical gay agenda" that wants to "turn everybody gay."
Global warming on the other hand is about predicting climate impact of human activities based on, you know, actual data. It so happens that the results are convenient for people who have a strong environmental ideology, but that does not mean that the science itself is motivated that ideology any more than epidemiology is driven by ideological agenda to blame things on microbes.
But here's the thing about global warming: facts matter. The earth is getting warmer or it is not (it is.) This will have a large scale disruptive impact or it won't (it will.)
Now, you can continue to argue against it on the basis that it's just a bunch of tree hugging hippie crap, but at the end of the day, someone is going to have to pay the bills for all that widespread disruption and those people are going to tend to be fiscally conservative big business CEOs of insurance companies. Republicans, in other words.
So, while we're all sitting around trying to culture up a nice vaccine to cure "teh gay," who do you think these rock-ribbed, no-nonsense, steady-hand-on-the-wheel, steely-eyed men of action are going to want to listen to when they're deciding how to underwrite drought insurance?
Will it be:
A) the 99% of the scientific community who can demonstrate to them the range of effects they can expect?
or
B) the Heritage Foundation think tank that says we won't have to worry about it because we're all gonna get raptured up before things get too bad?
