Yes, let them be shitholes, but how do you stop them from spreading?

 The Colonel talks about Democrat cities reaping what they have sown.

It’s very clear that these voters have voted for the rule requiring they be passive observers to crime, so when the witnesses shrug as thuggo goes to town, we need to understand that the city dwellers’ situation is their own doing. You can’t get a gun permit in SF or NY, yet someone expects you to take on a criminal who is not going to observe those legal niceties? How could you expect that? If you want to build a house, you don’t ban tools. If you ban tools, it’s reasonable to assume you don’t want any construction.

As every state in close proximity to Kalifornia can attest, Scat Fransicko doesn't stay in the Bay Area.  It relocates once the cesspool it has created becomes to toxic, and spreads the toxins to neighboring areas.  Downtown SLC isn't covered in trans/gay/schitzo flags because the local LDS folks decided it was a great thing to do.  Colorado didn't turn into a socialist weed-smoker's paradise because the locals really wanted ganja and oppressive government.  Seattle and Portland, well, a lot of that is homegrown there but a lot was imported from other areas.  And the people around cities like Portland still can't learn from their own mistakes.

Mayor and Police Commissioner Ted Wheeler, who defunded police upon real threats by Antifa and BLM rioters, just announced that, gee, we need more cops. He’s throwing money at retired cops to come back and also planning to spend more money to reimagine policing. Yet, another money-sucking grift as well as a paean to Antifa and BLM that will solve nothing.

"Reimagine Policing"?  Yeah, you're going to need to do that since the cops are leaving in droves, and yet the people of Portland keep voting for Marxist idiots who continue to plow the city into the ground.

And then they move to where you are.  So let the shitholes be shitholes but how can you keep the shithole people there?  That's the question I want answered.
