From Wikipedia, Sumner's "Crime Against Kansas" speech.....
Sumner then attacked authors of the Act, Senators
Stephen A. Douglas of Illinois and
Andrew Butler of South Carolina. He said:
"The senator from South Carolina has read many books of chivalry, and believes himself a chivalrous knight with sentiments of honor and courage. Of course he has chosen a mistress to whom he has made his vows, and who, though ugly to others, is always lovely to him; though polluted in the sight of the world, is chaste in his sight -- I mean the harlot, slavery. For her his tongue is always profuse in words. Let her be impeached in character, or any proposition made to shut her out from the extension of her wantonness, and no extravagance of manner or hardihood of assertion is then too great for this senator."
According to Hoffer (2010), "It is also important to note the sexual imagery that recurred throughout the oration, which was neither accidental nor without precedent. Abolitionists routinely accused slaveholders of maintaining slavery so that they could engage in forcible sexual relations with their slaves."
[23] Sumner also attacked the honor of South Carolina, having alluded in his speech that the history of the state be "blotted out of existence..."
[24] Douglas said to a colleague during the speech that "this **** fool Sumner is going to get himself shot by some other **** fool."
[25]
Well, Mr. Douglas was wrong.

Seeing as how he had that cane......
It's the Wigfall connection, folks.
