If people moved to the suburbs, then voted to put rules in place to maintain the reasons they moved there in the first place, that’s choice. They chose to move to the suburbs. They chose to create those rules. If that’s what they want, and people come to town and try to turn it into something else, they’re going to have to keep moving, which they don’t want, so they vote to keep things the same.
People can choose how urban or suburban they want to be, by choosing a community that fits what they want. Don’t move to a cookie cutter suburban area expecting it to change to fit your desires. The current setup evolved over decades and won’t change over night, and it is the way it is, because people wanted it that way (at least at some point in time).
If people wanted to change the rules of the city, they’d put it on the ballot and vote. If this isn’t happening, it’s because they are choosing not to. This doesn’t mean people don’t have choice, it just means that if you want something different today, you need to choose somewhere else to live. The alternative is choosing to get involved in local government and working to change those rules, and getting the citizens on your side. That can be a long road, but someone fought to do that in the past.
There are a lot of reasons people may not want to live next to a bunch of rental units or low income housing. Call them names if you want, but forcing this on them is taking away their choice.
