Need for separation / secession?

Some people seem to think that secession is no longer acceptable, which seems odd to me since our country was founded on secession. The only instance that is taught in school is the civil war and because of the association with slavery, secession is painted as racist, and no mention is made of the North Eastern states threatening secession on more than one occasion. I wonder if it is going to take states threatening secession to get some needed changes in our federal government.

"The problem that our nation faces is very much like a marriage where one partner has broken, and has no intention of keeping, the marital vows. Of course, the marriage can remain intact and one party tries to impose his will on the other and engage in the deviousness of one-upsmanship. Rather than submission by one party or domestic violence, a more peaceable alternative is separation. I believe we are nearing a point where there are enough irreconcilable differences between those Americans who want to control other Americans and those Americans who want to be left alone that separation is the only peaceable alternative. Just as in a marriage, where vows are broken, our human rights protections guaranteed by the U.S. Constitution have been grossly violated by a government instituted to protect them. The Democrat-controlled Washington is simply an escalation of a process that has been in full stride for at least two decades. There is no evidence that Americans who are responsible for and support constitutional abrogation have any intention of mending their ways. ... Americans who wish to live free have several options. We can submit to those who have constitutional contempt and want to run our lives. We can resist, fight and risk bloodshed and death in an attempt to force America's tyrants to respect our liberties and human rights. We can seek a peaceful resolution of our irreconcilable differences by separating. ... The bottom-line question for all of us is: Should we part company or continue trying to forcibly impose our wills on one another? My preference is a restoration of the constitutional values of limited government that made us a great nation." --economist Walter E. Williams
