>I think the landlord here is obnoxious

Agreed, but he is within his legal rights.

>I understand that you don’t see it.

I do see it. I just disagree that the way you stated would be worth trying. There are proper channels to handle this as a tenant that are legal and would get minimal pushback from the landlord. Such as:

• placing an opposing sign in your window.
• informing the public of the law, such as on Reddit
• speaking with those who can vote in your areas
