Uh...no, I don't have to accept collective responsibility for our elected representatives, because I didn't elect all of them.
The ones I did elect, I pretty much agree with. However, there are some real gems in the pack, elected by folks who are a lot less demanding of their elected officials than I am...or maybe they're just racist assholes (the voters, those they elected, or both). We in the US are slowly drifting in a more authoritarian, xenophobic and racist direction and there are still those of us who do not like this one bit. Unfortunately, the corporations (who are now "people", thanks to Citizens United) have a lot more money and seem to like this state of affairs just fine.
Thanks to the First Amendment, I can still say that second paragraph out loud.
