No, Galileo’s dissent from the Inquisition is not detail-for-detail like the skeptics dissent from the climate nonsensus, but it is close enough for political work.
In the New York Times’ “Divining Perry’s Meaning on Galileo Remark,” reporter Henry Fountain gets Augustana College historian Thomas F. Mayer to comment,
If Perry means to say that at some point some body of scientists said Galileo was wrong, that didn’t happen… His notions about science were not that far out there. There were a lot of other scientists, especially in Rome, who more or less agreed with his scientific observations.”
But Perry’s general point was that Galileo was punished for publicly dissenting from the church-approved dogma. Today, climate skeptics are disparaged and even threatened with criminal punishment for dissenting from government-approved climate dogma.
Yes, Perry could have made his point more articulately, but under the circumstances he did just fine.
