Of course there's going to be a backlash.  We're already seeing it.  Trump's poll numbers are going up.  I agree with many of Don's posts.  But you agreed with his entire post?  I think that the defund movement is doomed to failure because the movement is so nebulous and cavalier about how it would address fairness while allowing the police to protect people.  Sending psychologists into dangerous unpredictable domestic disputes is an idea that most people see as just silly and unworkable.  People with the privilege of living in nice comfy crime free households don't have to worry about the police being available to help them if needed.  But there are many people who don't have that privilege.  And the protests and the defund movement is pushing them back to the republican fold.
		
		
	 
Another side of oblivious privilege is when white affluent people don't bother to ask people in those neighborhoods just why it is that they so often do NOT want police coming into their neighborhood. 
Of course, from that privileged view, you can also say without the slightest irony that all incidents where police are called actually need police. People with all kinds of problems that do not require police end up being harassed, brutalized, or murdered by police who were not needed to begin with. 
The defund movement is about policing what needs policing and no more, and not every single incident treated as a dangerous crime.
You're right - it is very easy from a position of privilege to think that every neighborhood benefits from police "protection."
