Don't we all fall into this trap. We believe such and such and think "everybody" else agrees with us.
We have politicians who get elected by a majority or even a plurality of the votes cast and claim that they have a "mandate from the people". Does that mean that people who didn't vote for them or didn't even bother to show up are not people?
We have demonstrators who claim that they represent the wishes of the people. Maybe the wishes of "their people", but the rest of us are opposed to them, agree with them but are lukewarm about the issue, or could care less about their issue.
There are writers all over the political map who think they are making statements that "the people" care about an issue as much as the writer does. Maybe the only "people" that care are the editors who can fill some space with material that shows the editors "cover both sides".
In the side bar of a Huffington Post page, the following caught my eye: How Many Anti-Pot Politicians Will be Ousted Before They Realize the Will of the Majority?
Excuse me, but I could care less about the use of marijuana. Well, not quite. I care very much if you smoke it around me. Just like tobacco, one should not force others to participate in one's indulgences. I do care that a lot of tax money is used to enforce use of a substance. Prohibition showed the futility of that. Punish the public use or damage to others caused by use of certain substances.
