More incomplete historical ignorance.
Even this PBS show -- a station that caters to liberals/leftists/progressives -- had the historical prowess to realize the great impact that CHRISTIAN conservatives had within the abolitionist movement of the 19th century in the 1830s thru 1860s:
See: The Abolitionists to update your lopsided, incomplete historical vantage point on this.
The period to which I referred to was pretty obviously that from the end of the civil war to the 50s and 60s.
You care to provide some sort of evidence of conservatives playing a leading role in this struggle during that period?
Many Christians were abolitionists. The leading groups involved were Congregationalists, Unitarians and Quakers, none of which were considered conservative at the time, and which have continued their leftward drift since.
Abolitionists were NOT considered conservative by anybody at the time. AAMOF they were considered by most to be wild-eyed fanatical ideologues, even in the North, until well into the War. The leaders in the fight against slavery were called Radical Republicans for a reason, and it wasn’t because they were radically conservative.
