Darwin, like most 19th Century evolutionists after him, was a classical liberal. The political party he belonged to, the Whigs, is the one that gave rise to the Republican party in America. (Lincoln, born on the same day as Darwin, was also a Whig.)
Conversely, many opponents of evolution were classical conservatives. They were suspicious of free enterprise, aghast at social mobility (and abolitionism), and wanted to maintain the priveleges of the (established) clergy and aristocracy. Some of the strongest denunciations of Darwin and evolution were published in Tory journals.
This might have been the case - - - true in England . . . but not America // the opposite ! ! !
