A home should be a safe place from mobs pretending to express free speech but really intending to frighten those they disagree with, including the families and neighbors. Public squares are for politics and protests.
You're describing the Antifa and BLM mobs screaming outside people's homes.
This bill is about leaving a flyer on someone's property, and doesn't address mobs.
To keep the home “safe” you put society in the hands of the thought police. They will not be on the side of small government and individual freedom. The illusion of protection will dissolve in the reality of oppression.
Those posters supporting these kind of laws are inviting the “thought police”, gestapo into their own neighborhoods. You will only be allowed to promote the “right views” the State views.
