A typical response from a typical statist who believes that the federal government is the almighty power and controller of all things, which was precisely Lincoln's position.
The hotheads were the abolitionist and radical republicans. The conservatives of the day were the Southern democrats who, following Jefferson's timeless words in the Declaration of Independence, (We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.--That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, --That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness.) separated from the radical republicans. Lincoln ordered an invasion, which was a criminal act regardless of how you look at it, and proceeded to oversee the slaughter of 600,000+ human beings and the wanton destruction of an entire section of the country.
Timelines do count in history...
So does truth...
Exactly which unalienable rights had the Buchanan Administration so egregiously violated that secession from the Union was the only answer?
