I think just saying that helps ensure that people will get their own advice if they can. Though in theory attorney client relationships or fiduciary duties could be made and broken anywhere.

I think the landlord here is obnoxious. Instead of viewing them as impenetrable god, I am inclined to find some argument that I think is not frivolous to raise. I understand that you don’t see it.

Is that legal advice? If I rented you a car with a normal rental contract and then I got the car out for you and it had swastikas all over it, would you not have a basis to demand a car without swastikas or at least terminate the contract on that basis? I am not going to tell someone it is frivolous to try or at least make the demand.

(Still not legal advice).

You could make the argument that to the extent the lease allows the landlord to force expression on you, the lease is unconscionable or against public policy (especially without allowing you to put your own political signage out there).
