.... GAWWWDDD. What a thread....
There are no States petitioning for secession. There are citizens within states recruiting signatures for secession to send to Washington. Such petitions could be created by anyone on any topic, as is our civil right, but have no "standing" at all. Each administration does a thinktank among themselves to decide how they are going to handle such citizen petitions in terms of simply ignoring them or giving a public response. The current administration decided just as a guideline to respond to petitions containing over 25,000 signatures. This doesn't say what that response has to be because the petition has no legal standing. If petitioners start to attempt to bring court action [which can not succeed by definition in this particular issue] or petition to put something on an election ballot, such behavior MIGHT begin to come close to something actually legally serious. At least in such a latter case, the petitioners could claim that their state's electorate supported it in the majority. That might put it in analogy to the situation in Quebec.
These actions are either: a]politically inspired to attack the current administration [the chances that those petitioners would say that they actually hate America is around zero]; or b]. primal scream therapy for those who hate the current administration and who feel powerless to do anything. One can choose to join in such behavior, "understand" and sympathize with such behavior but do nothing, "be understanding" of people with frustrations while not buying their reasons, or view these people as unhelpful to the general progress and civility of society and express one's displeasure with them. All four sorts of Americans should realize that this is, however, nothing with any general nor legal force to it, unless it would develop into a movement "in the streets" a lot larger than it is now. It would have to become the conservative libertarian equivalent of the social movements of the 60s. And that would mean some violence and "civil disobedience".
