Maybe I am jaded, but the various memes on facebook are somewhat selective. They fit into certain preset patterns that are predictable. One of these was to show "support" for France by overlaying your profile picture with the three colors of the French flag. Yes ISIS attacked French people going about their own business. With that in mind, let's talk about another attack by ISIS on those minding their own business.
From Reuters:
President Vladimir Putin vowed to hunt down those responsible for blowing up a Russian airliner over Egypt and intensify air strikes against Islamists in Syria, after the Kremlin concluded a bomb had destroyed the plane last month, killing 224 people.
So can I conclude that I will be overwhelmed with the number of people announcing they are "supporting" Russia by changing their Facebook profiles with an overlay of the Russian flag? It is the same colors, so no work is necessary for those who already have supported France.
I won't hold my breath.
