I know you think it's a good look in your neighborhood to put a "Stop Demolishing Portland" sign in your front yard, but did you ever stop to consider that maybe you're an asshole?
Someone is going to move in to that "ugly monster home" you're staging your pretentious protest against, and odds are they're going to be a friendly, left leaning family just like you! What a nice welcome to the neighborhood you've given them!
All these "historic" homes with "character" you're grieving the loss of were once the unwelcome development of their time. How about we embrace the fact that change and development are a part of every city everywhere and celebrate the fact that we can now design houses with modern lifestyles and energy efficiency in mind?
Take down your passive - aggressive yard sign and bake a batch of cookies instead. You'll feel better about yourself and your community.
