Part of the logic of historic preservation as cultural resource management is that it really can’t be imposed from without. If people don’t like a building, calling it a landmark won’t make them like it more. (This was, in my opinion, why the effort to save the Huntington Hartford Museum failed, and the building was altered to the point of being unrecognizable. You will search long and hard to find praise for the original building dating from the period before it was scheduled to be altered.)
There is currently a research project being run by three people at Columbia University’s Graduate School of Architecture, Planning, and Preservation* that is actively looking for people’s opinions about preservation, specifically on historic districts. There’s a nice write-up here and the survey is here. Let your voice be counted: be a data point.
* Conflict note: I teach at Columbia as an adjunct. I am not in any way involved with this research project.
