Charlie Hebdo and solidarity

There was a huge march in Paris yesterday to demonstrate solidarity with the slain staff members of Charlie Hebdo, the satirical French magazine.  Millions of people throughout the country, many of whom would have considered the magazine tasteless and crude, declared their allegiance to Charlie and by association with free speech.  I did not detect much in the way of support from Americans.  Aside from a few reports of the demonstrations, most networks concentrated on football and the Golden Globe awards.  I suppose we could not be expected to feel the same emotions as the French since we didn't lose any citizens to a terrorist attack.  However, I wonder if the staff of the Onion or another satirical rag in this country was massacred would Fox News and other right wing opinionators be as outraged as the situation would demand?
