Chesterton's meta-fence: "in our current system (democratic market economies with large governments) the common practice of taking down Chesterton fences is a process which seems well established and has a decent track record, and should not be unduly interfered with (unless you fully understand it)".
? I think the definition I use of Chesterton Fences may have expanded somewhat, until it's almost equivalent with Burkean conservatism, or a general argument against "we think that changing something traditional in society will bring benefits, so let's change it".
De gustibus, of course, but I prefer limited and hard definitions to ones that fuzzily expand until they're "almost equivalent" to a large and vague concept...
