Indeed. Aside from being extraordinarily intellectually lazy, bothsidesing actually enables corruption by failing to identify it, or failing to distinguish degrees of corruption that are so severe as to be more differences in kind than differences in degree. And thus in the U.S. we get Trump and his entire cabinet, Clarence Thomas and the rest of the Federalist Society, the Kochs, money pouring into elections via Citizens United courtesy of John Roberts, and much of the rest of the GOP political apparatus ... in large part a result of people staying home or voting 3rd party because their "principles" didn't let them vote for "the lesser of two evils".
It's not intellectually lazy, it's being intellectually tired.
Both parties only every get anything done in this country when it comes to voting to restrict our rights. Ideologically, I'm slightly right leaning. My primary value is individual rights are more important. But if I could, I would vote for Ron Wyden(D) despite the fact that I disagree with many of his positions, he's still one of the few that has a spine to oppose things like the federal spying apparatus.
I just don't see the point of investing myself in caring when 98 percent of our reps just really don't care and only focus on manufacturing outrage around wedge issues that they can't or won't actually address so that they can keep their jobs and continue to accrue massive amounts of wealth from lobbying and insider trading. We get Trump because the system is so thoroughly broken on both sides and enough people are frustrated the point that they are "protest" voting.
