I think all anyone can say right now is to hope for the best for those most affected by what's going on. I'm sure there are other ways we can help, more directly. But again, this is all still kind of fresh for me right now.
That said, there is something else I'd like to say, and I think the following is relevant at any time:
If anyone takes this pointless chaos, this senseless destruction as an excuse to shit on refugees, immigrants or just Muslims specifically, OR thinks this is the perfect time to make that sweet "France surrendering" joke you've been holding onto since the 1940's?
Punch yourself in the balls instead.
If you have ovaries, punch those instead. If you have more than one set of genitalia, please take time out of your schedule to ensure they are all punched adequately.
Keep punching until you remember what pain is, because if you think posting that shit on Facebook or whatever makes you a good person, you've clearly forgotten that people feel hurt.
