Elected, yes. Thoughtful and responsible depends on your point of view. For example: there is a substantial contingent of people in the U.S. that want the country to be a Christian theocracy. (Most of these people believe that this is how things used to be, and they want to return to those halcyon days.) And so, unsurprisingly, these people vote for representatives who they think will advance that goal. So, for example, is Roy Moore "thoughtful and responsible"? If you're a member of this contingent then you probably think he is. If you're not, then you probably don't.
Likewise, there is a substantial contingent of people who are scared witless at the thought of terrorism, and think that it's worth trading in the odd civil right to insure that terrorists are not "free" to plot our destruction unmolested. There is a substantial contingent of people who are unrepentant racists who think black people are less than human and the root of all evil. Likewise for Muslims. All of these people not only don't care when "the bad guys" have their civil rights violated by the cops, they think it's a feature. They see the cops as courageous defenders of their point of view against the corrupting influence of pluralism and wussiness. The vaguaries of our electoral system make a difference at the margins (e.g. by gerrymandering) but none of these things would be possible if there were not millions of people who thought that it was good and proper.
The irony is that by blaming the system instead of acknowledging that the outcomes we see are the result of democracy working exactly as intended you are actually contributing to the problem, which is that everyone retreats into their echo chamber and spends their energy vilifying anyone who doesn't agree with them instead of working constructively to figure out how all 7+ billion of us are going to get along on this little planet.
