One said, "F*** Biden" and the other, "Only Gay Cops Pull Me Over." I suppose the driver has a First Amendment right to utter such garbage, but the second one seems intimidating and hateful. That's life in the post-pandemic now.
The second thing I spotted was a license plate frame that was much lighter in tone and actually funny; the top said, "I Know I Know" and the bottom part read, "License and Registration." Nothing vulgar there; American humor has survived.
