Hard for me to feel sorry for landlords in Leftist cities like Seattle. Seriously, how did they think it would end, with that bunch. The writing was there, just as it was with Hitler’s extermination camps, but if the soon-to-be victims refuse to see it and take action (in this case selling their properties while it was still possible), then they will suffer the consequences.
By the way, if a city like Austin tried that stunt here in Texas (if it is even legal), our Legislature would be called into emergency session and quickly put them in their place...which is why you don’t see Leftist cities here enacting gun control - won’t happen as long as Republicans rule the state (and that will be for far longer than many here believe).
You get what you vote for, good and hard.
