It's useful, in how anti-science nutters like Kosh are willing to instantly identify themselves as such. Once you see some cult bedwetter whining about how global warming is a fraud, you know instantly everything they say should be assumed to be a lie, unless independent evidence shows otherwise.
Some nice strawmen on the OP's list. I've never encountered any of these people listed below. I suppose since actual anti-science positions held by liberals are in short supply, some had to be manufactured.
fetal life deniers,
"sex has nothing to do with reproduction" people
"evolutionary psychology is sexist" people
Anti-science positions are scarce among liberals because liberals are willing to tear their own whenever a liberal utters such stupidity. We ripped into the anti-vaxxers, we ripped the anti-GMO kooks, so they've been moving to the more conspiracy-friendly conservative side. Conservatives may not criticize fellow conservatives, no matter how crazy the conspiracy theory.
Depends on how you define an anti-scientific position.
Take evolution theory. The majority of people aren't particularly well read on the subject and know only the basic concept, to the degree that is common knowledge. Yet many of these people, including many "liberals" still believe that they -know- evolution theory is factual because they've heard that "science" knows it. Blindly accepting as fact what trusted sources have told you is "scientific concensus" is not only not a scientific mindset, it is actually incurious and thus anti-scientific.
The sad fact of the matter is that mostly everyone is anti-scientific in their mentality, and this incurious nature isn't native to any political affiliation.
