They may be intended to be clever and ironic, but...
They do seem to be rather aggressive, at least at first glance. They take their style from the "Keep Calm Carry on" series of World War II posters, available from Barter Books, of which my favourite is shown here.
I have this poster, and plan to display it in my front window - it may be possible to subvert this poorly targeted campaign for the cause of liberty.
