Gosh, as I recall, John Brown's activities at Harper's Ferry were put down by federal troops and Brown hanged. That some people justified his actions does not mean it was government policy.
But again, it is really the grievance admitted by Webster, even in denouncing the very idea of disunion, in his classic 1850 address, which goes to the lack of respect for partners in a once honorable coming together.
Proving how far the north was willing to go to appease the south. But that wasn't enough for them.
People like Washington & the Virginia Lees, understood America as a project among honorable men, who respected one another & their respective contributions, but sometimes differing perspectives.
That would be the Washington who said:
The unity of government which constitutes you one people is also now dear to you. It is justly so, for it is a main pillar in the edifice of your real independence, the support of your tranquility at home, your peace abroad; of your safety; of your prosperity; of that very liberty which you so highly prize. But as it is easy to foresee that, from different causes and from different quarters, much pains will be taken, many artifices employed to weaken in your minds the conviction of this truth; as this is the point in your political fortress against which the batteries of internal and external enemies will be most constantly and actively (though often covertly and insidiously) directed, it is of infinite moment that you should properly estimate the immense value of your national union to your collective and individual happiness; that you should cherish a cordial, habitual, and immovable attachment to it; accustoming yourselves to think and speak of it as of the palladium of your political safety and prosperity; watching for its preservation with jealous anxiety; discountenancing whatever may suggest even a suspicion that it can in any event be abandoned; and indignantly frowning upon the first dawning of every attempt to alienate any portion of our country from the rest, or to enfeeble the sacred ties which now link together the various parts.For this you have every inducement of sympathy and interest. Citizens, by birth or choice, of a common country, that country has a right to concentrate your affections. The name of American, which belongs to you in your national capacity, must always exalt the just pride of patriotism more than any appellation derived from local discriminations. With slight shades of difference, you have the same religion, manners, habits, and political principles. You have in a common cause fought and triumphed together; the independence and liberty you possess are the work of joint counsels, and joint efforts of common dangers, sufferings, and successes.
But these considerations, however powerfully they address themselves to your sensibility, are greatly outweighed by those which apply more immediately to your interest. Here every portion of our country finds the most commanding motives for carefully guarding and preserving the union of the whole.
The Washington quote, of course, absolutely presupposes the "mutual respect," that underlay the achievement of the unity he describes. But, then also, Washington states:
In contemplating the causes which may disturb our Union, it occurs as matter of serious concern, that any ground should have been furnished for characterizing parties by geographical discriminations,--northern and southern--Atlantic and western; whence designing men may endeavor to excite a belief that there is a real difference of local interests and views. One of the expedients of party to acquire influence within particular districts, is to misrepresent the opinions and aims of other districts. You cannot shield yourselves too much against the jealousies and heart burnings which spring from these misrepresentations; they tend to render alien to each other those who ought to be bound together by fraternal affection.
While the misrepresentations may have flown from both sides by the panic of 1857, they started as an attack on Southern society, well before the Southern "Fire-eaters" responded.
