I forgot to add Centrist into the mix, as it also doesn't actually mean anything, just like independent, moderate and unaffiliated. Together they are the emo-gothic rejects of politics, uniform in their anti-conformist ways. An ironically paradoxical existence.
As these labels are not expressions of belonging or allegiance, the instant an opinion on any issue falls on the conservative or liberal side, however slight, that person becomes a lair; they claim they are not of the lean which their position resides. All opinions fall to one side or the other, there are no exceptions.
Those who reserve opinions so as not to fall on either side of an issue, are the cowards; they are afraid to take a stand, even a reasonable one.
