While it is a touch off your personal encounter, if there is a particular super-user "dolphin, whale" disagrees with you or simply doesn't like yo, they can effectively silence you or vote you down to nothing and "suppress" you.
Really sad. That's the argument against Anarchists. As you say people think splitting off and having their "own" government and society means freedom. Bt you get the same thing as before : Some person will get thirsty for power and start the oppression once again.
That's human nature. Why do anarchists think things will be any different when they find their "utopia"
Exactly, 100% correct.
But it's THEIR utopia, so it's ok for a few of them.
And that is pretty much all it is, as long as it benefits them. It really isn't a structure issue but a human nature issue.
