Apparently, this is from a protest in the UK, where they understand a bit more about what is and isn't protected speech. Several of these protesters are now in jail for incitement to murder.
Check out some of their other signs:
"Butcher those who mock Islam"
"Behead those who mock Islam"
and
"Be prepared for the REAL Holocaust"
Real class acts.
