No, this has nothing to do with English grammar. I understand that you are using "you" in the plural, here. What I reject is the premise that "Americans" is an identifiable group that is collectively responsible for any particular thing, extending to people who never supported or voted for that thing.
This is a philosophical disagreement, not an issue of language.
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.
