Paris: At least 128 dead in 6 terrorist attacks

Okay, so people made "PrayForParis" for a reason (and don't get me wrong, I'm with it despite not posting about it). Not even 24 hours later, I start seeing people talk about other events that happened like PrayForJapan, PrayForMexico, and others. Now it's "PrayForTheWorld"? Am I the only one that find this eerily similar to how people changed "BlackLivesMatter" to "AllLivesMatter"?

Not trying to cause any kind of ruckus. Yes, yesterday was a horrific day in different parts of the world, but why change a hashtag/phrase that was created to identify events? It happened with BlackLivesMatter when others said "No, EVERYONE matters". In my mind, I'm reading this as "No, pray for the WORLD instead". I even looked up the earthquakes and the one in Mexico was relatively small with no damages/deaths, and the other happened 90 MILES off the coast of Japan with no imminent danger at all. How were these events relevant and need praying? The tragedies that's happened are being washed-out by these hashtags and it's infuriating.

I partially agree with you, and partially don't.
While it's true that equating what happened in Paris with harmless earthquakes cheapens it, I do think we need to PrayForTheWorld.

The events in Paris weren't an attack on Paris, or even on France, alone. They were an attack on the West, on the civilized world, on everyone who isn't (the "right" kind of) Muslim. The attackers chose Paris for various symbolic and logistic reasons, but their previous strike was blowing up the Russian plane taking off from Egypt, and their next target could be Sydney, or Washington, or The Hague, or Mumbai, or even Tehran (they did attack Hizbolla, the Lebanese fundamentalist Islamic organization backed by Iran and the Syrian regime).

So yes, PrayForParis, for the wounded, the bereaved, and the scared people there; but also PrayForTheWorld, because, make no mistake, we are in a World War.
