I did add the French flag overlay on my FB but many of my friends didn't do so, not because they condone the shootings but due to FB's choosing of the seemingly deserving west and underserving others. Many of my friends queried why there hadn't been a Syrian, Lebanese, Iraqi or Palestinian flag filter.
I can't say I disagree but I admit I hadn't considered this until their posts came up on my feed. Did you choose to change your profile to include the French filter or did you decide against it?
I'm now going to change my profile pic back to normal because in the main I disagree with FB's double standards.
