What the heck am I supposed to do about it?

I think the burden is on the person with the sign- there's a limit to good taste, people. Unfortunately, not everybody will do so; and in order to preserve the "good" and "useful" speech, we have to protect the offensive stuff as well. The offensive stuff actually needs more protection which puts me in an odd place of nearly defending it. Either we have free speech or we don't.

I'll put my bets on "do" every time.
