Sorry, but the First Amendment trumps what you believe to be in “disgustingly poor taste.”
These memorials are not on private property against the will of the land owner, but are on public land.
Sometimes they may be at the corner of an intersection or on the side or the road or just off the sidewalk near a home or hospital where someone died or even sometimes near an abortion mill where thousands have been murdered.
Again, it is a First Amendment Right.
I disagree. These eyesores are all over the place. The right of way is maintained. That means the town/county/state/whatever cuts back grass(to prevent an eyesore and keep down down mosquitos and pollen). Postings of any kind interfere with that.
During elections, the easements bristle with wire/ paper election poster. These are removed by the highway depart right after elections. Freedom of speech acknowledged and is temporary.
If the highway easement is for all to exercise free speech then the roads will look like a third world slum as not only memorials but people selling everything imaginable posting there junk.
I firmly beleive in free speech. Doesn’t mean you can litter or put up signs anywhere you want.
