Workers at conservative think-tanks breathe oxygen. Ergo, breathing oxygen is wrong.
Labor unions? Bad! Climate change? Probably good, actually!
Their article on oxygen would be "oxygen is good, always" or "oxygen is bad, always". They don't leave much room for nuance in their encyclopedia, and unsourced assertions of a policies popularity in their writings can probably be treated with a grain of salt.
The best way to demonstrate that would be to link to a more neutral source, or sources across the partisan spectrum.
"Here's an op-ed by a conservative think tank about why taxes are bad" is gonna get people expressing very reasonable skepticism.
