In my time on Facebook I have seen many social awareness campaigns come and go. I generally don't participate in any of them. Several months ago women posted where they put their purse every night, (on the table, etc) under the guise of raising awareness for breast cancer. Right now many are changing their profile picture to their favorite childhood cartoon character, to raise awareness of child abuse.
I know I tend to be salty and cynical, but seriously, HOW is this helping anyone? I'm sure not everyone will agree with me on this, but raising awareness is generally pointless if that is the end goal. If you talk about it, and cheer for the cause, and get a warm fuzzy feeling, you have essentially done nothing for the cause. You've done just enough to assuage any guilt you may be carrying, but you haven't actually helped anyone. Put your money where your mouth is, and DO something. Go volunteer, raise money, donate, get your kids involved to teach them, speak out in tangible ways.
For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand that we should walk in them. ~Ephesians 2:10 God made us to do good works, not just talk about good works. Get busy!
