In democratic system(please spare me "we're republic not a democracy" adage that every American spewes) every citizen votes, and shares responsibility in decision making process.

You can become politically active and try to convince others if you don't like current status quo, inaction is also a choice.

Unless you think US isn't a democratic country but authoritarian one(either oligarchy, technocracy or whatever - does not matter) then it is definitely not a philosophical disagreement, but lack of responsibility and wishful thinking.

> every citizen votes, and shares responsibility in decision making process

Why? I never consented to be a part of the system, don't agree with it, and in practice can do nothing to change it. Saying I'm responsible for it because I happened to be arbitrarily born with a particular citizenship is meaningless.

> In democratic system...

There is no reason why I, an unrelated individual, should have to ascribe to the ideals espoused by proponents of the system imposed on me without my consent.

You might not believe in system and ignore it - your choice. but it exists.

You live in it, and it is part of your reality so your only choices are to emigrate somewhere undemocratic, or be part of it.

It is pure denial of reality otherwise.
