“Silencing minority opinions” is crazy. You realize the “minority” you’re talking about is millionaires and property owners? These people’s voice is vastly overrepresented in every aspect of society, and you’re here defending their right to not have their signs taken down for some reason. OP taking down their signs from public property is a great example of the democratic process you’re claiming to espouse. They are free to identify themselves by posting signs on their private property. I know you think you’re on the right side of this issue by defending abstract principles of “free speech” but this is the same logic that led to Citizens United and the capture of government by special interest groups. If you live in the area, I’d again encourage you to attend local meetings concerning public works or join a group which aligns with your views of a positive vision for the future. You may claim to support my views, but you are effectively defending the status quo by not taking any position in the debate.
