This seems to be mainly about billboards. I’m talking mainly about a sign on your door that explains what your business is. I hadn’t initially thought of this as a form of advertising but it technically is.
I’d be open to discussing a broader ban but my current thinking is that this very basic type of advertising which is primarily informational may be do more good than harm.
This is just not in any way accurate. Free speech means the government cannot penalize anyone for speech with specific narrow exceptions. Deporting them for such speech is obviously penalizing them. Laws or no, this is unconstitutional.
