In all seriousness, those fb filters are purely symbolic and will not do much for the injured/deceased. We are on our own. At this point, it's best to remember the victims and put our money where our mouths are until we get to the root of this tragedy.
Guys, don't feel sorry for yourselves. Don't seek sympathy. There's no help on the way. Help can only come from within. If you help yourselves, you will get to take credit for what you achieve, without being forever indebted to onion-eating robed people or the west.
