Yeah, I know there's a lot in the world to criticize right now...but don't get caught up in only doing demolition. It's fun. It feeds a certain part of us that feels torn down itself, but don't get caught up in it. Your energy is better served in building new things, not just demolishing the old. 
We can talk about what people are doing wrong all day but let's also help build.
A good contractor will do demolition on the old structures in place but they won't go crazy all over the joint. They tear down the old and then grab the tools and start building again. Let's help folks grab the tools and build.
