Don't protest at the station, go after their license. This can be done remotely and if enough people complain it might do some good. Find factual instances (date time of story), where the station has sewed division for the purposes of ratings instead of bringing the community together. Call out their racism in network shows and how they disenfranchise people based on race - politics or anything else, call out every slight they do even if its small.

Don't just say that they are pro or against trump, That is low effort and not going to be effective. But rather make complaints that are thoughtful and factual on how they are abusing their power, and remember this will be a public record. Don't leave them any room to say they will do better, but make clear cases where they chased $$ instead of building up the community for public good. Show a continuous pattern of exploitative behavior.

This is not about taking away their speech but really illustrating how their broadcast license is a privilege not a license to print money. The need to show how they are an actual benefit to the community. Be ruthless but smart in your complaints.
