... and many of the *-libertarian schools are radically opposed to each other.
1.) They describe different means of achieving supposedly similar
goals.
Individuals in a given school have
different means of achieving the
same goals; at the same time, an
anarcho-capitalist and an
anarcho-communist might agree on to how to achieve
different goals. I can't agree that your point is valid.
2.) Some individuals realized certain definitions are no longer
valid after they've been hijacked via mis-used
by others
Whenever this happens, the individuals who
feel a certain label has been hijacked will usually abstain from
denouncing the
label, and will instead denounce the
hijackers. Many
libertarians abstain from calling themselves "libertarian". If asked
why, they'll almost always say, "Well, I was a libertarian, but
non-libertarians have hijacked the meaning of the word, so I prefer
x". They will
never say, "I disagree with what libertarianism stands for".
or 3.) Some
individuals arrived at similar conclusions in developing thoughts, but
placed different labels upon them, or possibly didn't label them at
all.
Like I said, if those individuals find out about
anarcho-capitalism and decide they don't agree with us, they
aren't anarcho-capitalists!
I agree with Brainpolice when he says that anyone who believes in voluntaryism is working towards the same goal. In fact, I don't care what label we use (I'd prefer if it didn't involve the words "anarchy" or "capitalism"...).
I'm more than willing to work with anyone who wants to shrink the government, regardless of whether they are anarchist.
Don't allow leftists to play games with definitions! Some of the
libertarian-leaning leftists at this forum will try to redefine
"left-wing" back to its original defition (Third Estate, limited
government, free-markets, laissez-faire reforms, etc.). Fine! We
non-leftists can't stop them from using their own personal definitions;
they can use whatever labels they want to describe any concept they
want.
However, they have the audacity
to then use their personal definition of "left-wing" (remember, the original
definition, which is no longer valid) to prove that modern leftists are
more libertarian than modern rightists! They will say that
libertarianism is "inherently leftist" (again, using the original, no
longer valid definition), and use that to insist that we should prefer
and side with modern leftists over modern rightists.
Question their motives.
