Americans introduced the hash tag #PrayForParis. To which a Parisian replied "Friends from the whole world, thank you for #prayforParis, but we don't need more religion! our faith goes to music! kisses! Life! champagne and Joy! #ParisisaboutLife". I found that amusing, despite the fact I read it last night shortly after the attack.
It seems that American tweeps don't know that the French value their secular state. Which must seem odd to people in a country where so many people are still religious.
