I often find it mind-boggling the number of people who seem to think that updating their Facebook profile picture is an effective means of offering support for a worthy cause.
Don't get me wrong, there are certainly times when updating your profile image might "raise awareness" for a lesser-known issue of some sort (like saving sharks from extinction), or to show a sense of solidarity in a time of crisis (like the thousands of updated profile pictures in the wake of the terrorist bombings in France). But for the most part, updating your profile image is a meaningless act.
Here is a perfect example: some people will update their profile image with a pink ribbon in order to "raise awareness" for cancer. But what has this actually accomplished? Perhaps a few people might see the profile picture, but everyone on the planet already knows about cancer. What would be considerably more effective would be to actually do something about cancer. How about volunteering at a hospice? How about organizing a fundraiser for your local hospital? Or at the very least, how about personally donating to the American Cancer Society?
If there is an issue which you are truly passionate about, then you need to do something about it. March in a protest. Write your congressman or congresswoman. Speak out at a town hall. Work with others going door-to-door to promote your position. Organize. Plan. Act. Women's Suffrage and the Civil Rights protests of the 1960s would have gone nowhere if people simply sat at home and updated their Facebook statuses.
No, updating your Facebook profile does not make you an activist; it makes you a lazy non-contributor.
