If you have a military you're in direct violation of your pacifistic ideals. Pragmatism aside, military power is a show of force. If you have an army, you are a direct threat to every other country out there. People aren't going to just "follow suit", they'll make their own armies to prevent an invasion from you, if not to test the mettle of your forces. You can say you're a pacifist all you want, but the best you can hope for is that people will leave you alone, unless you have something they want. At that point, they'll just come over and take it. If you resist, as is the point of an army, there goes your pacifism.
I'd have an army just for show. It wouldnt be big, and our arms would be horible. I'd never use any money at all to make it better. I'd dropp it as soon as I'd have signed a contract with the surounding countries and agreed uppon certain anti-war issues.

A utopian society is an impossible ideal because we are human and by nature imperfect. Not everyone will agree with how to do things, and a world this large cannot be unified under one banner without a show of excessive force. Expecting things to fall into place because it's the "right thing" is asinine, not everyone agrees that your way is the right way, for one thing, and even if a general consensus were reached that your way was, indeed, correct, there would still be those who would detest it and rail against it. And as you profess to pacifism, that means that you might have an army, but you'd be loathe to send them out and actually fight, making it that much easier for the dissenters to walk all over you.
I agree that an utopian society might look impossible in our curent state, however as close as we can get is however a posebility.
What makes war?
Money, therfore we need to dropp money.
Religeon? we need to make sure freedom of speech is a respected reality in this field.
Also, pollution destroys humanity and animals, therfor we need to derstroy pollution.
Decease kills everyone, therfor we need to fight deceases, and we need to give people free health care so everyone can have a chance at this.

These are very basic things, as you see, but they are hard to reach. But the only one that might even look impossible today is the abolishment of cash, but we'll get there, eventually.

If you want to change humanity, you should start with the kids. It is perfectly possible to get rid of racism if kids are teached up to know that each race are equal, I guess you get where I'm going.
If some of these people were to protest, they'd be outnumbered by the democratic majority, untill their theory would eventually dissapear, like the burning of wiches dissapeared, and like the fetish rich English men had to see super deformed people (like the Elephant man).
Look, homophobia will be gone in the majority of the world in just a few years, I'm sure about that.

And yes, if sommeone protested, they would go in charge, I could of course take him to jail if I wanted to, becouse I would not be using violence to do that. If hes words reached to a majority, I'd just give him my possition. But I wouldnt be alive for that decission, I'm just saying that if I was alive, and everyone's admin, I'd do that.

An admin is just a basic regular person that makes sure that everything is in place in an anarco communistic society, I dont know enugh about this philosophy so I'd rather not go to that discussion.

I'm more concerned about how much freedom we can make.
We could remove Nazism. Some might dissagree and say that this is just the same as preventing the valuable "freedom of speech," but it isnt. It's just the same as to teach a child a different, more logic way of thinking then what theyr nazistic parents might teach them, they get to chose wether their parents are right about jews and niggers, or wether the friendly foringer isnt an exeption to hes race and nationality.
We need to start with the kids.
