Times like these tend to make all sorts of creatures come out from under their rocks.
While stupid folks on the fringe of left is fully capable of as much idiocy as on the right, I strongly disagree with simple equivalency between the two.
We are here due to the failure to curb the violent excesses of systemic racism in USA. The left is not the villain this time around.
It wasn't always true, but presently "left" is represented by Democrats and "right" is represented by Republicans. You have some exceptions, my governor for instance, but generally elected officials of the two parties represent a party platform. Local policing is overseen by the state and city governments.
Who has been in control of the city governments in most places where police brutality has been an issue?
We both know the answer, so I don't think it's safe, fair, or accurate to say that the left can be absolved. Ultimately, this shouldn't be a left/right issue. It shouldn't boil down to political confessions. It's a question of ethics. We can easily pin point it. We can see it. Therefore, it really shouldn't be hard (and the fact that it IS difficult has indeed largely been a facet of the right) to acknowledge this and find policy solutions.
What I am getting at is that the left is presently off its rocker. Normally, I wouldn't care about this. However, I really want to defeat Donald Trump. I have valid concerns with the direction of the current zeitgeist and how it will be interpreted by Americans other than true believers. So far, they have managed to damage Donald Trump's credibility and most Americans believe he has done a crap job of managing it.
The longer this goes on, the more outlandish, zealous viewpoints get put out there as part of mainstream consumption, however, WILL lead to a backlash. There will be unintended consequences. The left needs to reel in its fringe. Right now, it feels powerless to stop them. They're drunk on power.
I mean, really? Defund the police? What an albatross that is. The language is clearly at odds with a winning formula the left has found for other issues (e.g. pro-choice, marriage equality). There needs to be a serious rebranding and a serious discussion within the left as to how to package in a way that is palatable for Americans.
