There is no good reason to question the genuineness and sincerity of the fears expressed by the slave-holding population as a justification of their violent measures for the suppression of free speech in relation to slavery; nor of their belief that the papers and prints actively disseminated from the antislavery press in Boston were fitted, if not distinctly intended, to kindle bloody insurrections. These terrors were powerfully pleaded in the great debate in the Virginia legislature as an argument for the abolition of slavery.[281:2] This failing, they became throughout the South a constraining power for the suppression of free speech, not only on the part of outsiders, but among the southern people themselves. The régime thus introduced was, in the strictest sense of the phrase, "a reign of terror." The universal lockjaw which thenceforth forbade the utterance of what had so recently and suddenly ceased to be the unanimous religious conviction of the southern church soon produced an "unexampled unanimity" on the other side, broken only when some fiery and indomitable abolitionist like Dr. Robert J. Breckinridge, of the Presbyterian Church in Kentucky, delivered his soul with invectives against the system of slavery and the new-fangled apologies that had been devised to defend it, declaring it "utterly indefensible on every correct human principle, and utterly abhorrent from every law of God," and exclaiming, "Out upon such folly! The man who cannot see that involuntary domestic slavery, as it exists among us, is founded on the principle of taking by force that which is another's has simply no moral sense.... Hereditary slavery is without pretense, except in avowed rapacity."[282:1] Of course the antislavery societies which, under various names, had existed in the South by hundreds were suddenly extinguished, and manumissions, which had been going on at the rate of thousands in a year, almost entirely ceased.
The strange and swiftly spreading moral epidemic did not stop at State boundary lines. At the North the main cause of defection was not, indeed, directly operative. There was no danger there of servile insurrection. But there was true sympathy for those who lived under the shadow of such impending horrors, threatening alike the guilty and the innocent. There was a deep passion of honest patriotism, now becoming alarmed lest the threats of disunion proceeding from the terrified South should prove a serious peril to the nation in whose prosperity the hopes of the world seemed to be involved. There was a worthy solicitude lest the bonds of intercourse between the churches of North and South should be ruptured and so the integrity of the nation be the more imperiled. Withal there was a spreading and deepening and most reasonable disgust at the reckless ranting of a little knot of antislavery men having their headquarters at Boston, who, exulting in their irresponsibility, scattered loosely appeals to men's vindictive passions and filled the unwilling air with clamors against church and ministry and Bible and law and government, denounced as "pro-slavery" all who declined to accept their measures or their persons, and, arrogating to themselves exclusively the name of abolitionist, made that name, so long a title of honor, to be universally odious.[282:2]
