Placid, if I am understanding you correctly, you are essentially stating that your disillusionment (though perhaps displeasure might be a better word) with American democracy is not in the democracy but in the possibility of the majority disagreeing with your perceptions; if such a disagreement between the populous and yourself continues, you are quite willing to relocate yourself to a population group that better matches your views. In short, it seems that it is the degree of conflict between your views and the populous' views that you find so displeasing (and not just that there is a conflict of views).
Is such a correct understanding?
If so, allow me to follow such up with another question. What do you know of the term "bystander"?
I am not referring to the dictionary definition of the word, mind you, but to bystanders as a group of people as they are concerned to violent actions. To an extent, this includes the Bystander Effect, but I am also referring to a larger scale than that. When one talks of genocide, one almost inherent has to talk about three groups of individuals; the perpetrators, the victims, and the bystanders. Bystanders are individuals who witness actions that they are opposed to but are not involved with. Yet, not only are they not involved, they also refuse to get involved. While such individuals are not the perpetrators of a crime, nor are they the victim of that crime, they allow the crime to happen.
Why do I bring this up? I can well understand the frustration you might have over being part of a nation that behaves in a manner that you think it utterly stupid, foolish, and harmful. However, if you do, in fact leave America because of the conflict between your own views and the views of the populous, you are only turning yourself into a bystander. What ever ill follows, you have not washed your hands of it. Rather, you will have allowed those ills to happen.
Evil happens in the world because of the silence of good people.
Now you might think it doesn't matter if you stay in America or not, such ills will happen nonetheless. Perhaps, but you, and people like you, are a mitigating force in the United States. Without you and those like you, the government is free from the restraints that you provide. Those restraints might not be as powerful as you might like, but they are also more restrictive than nothing.
And that takes us back to my original statement. It would appear that you do not like democracy. I say this because without you and those like you, this democracy will fail.
Democracy's strength is not just in everybody agreeing on something but also in everybody disagreeing on, well, everything.
