I rarely participate in those Facebook causes. The last one I took part in was the cartoon characters one for child abuse awareness, and the only reason I did was because Sarah went into my Facebook account and did it for me. That, and it was kind of fun to see the cartoon characters.
What gets me about these causes is that I almost feel bad if I don’t take part because it makes me come off as an insensitive person. “Why don’t you have a purple profile pic right now? Don’t you care about saving the raisins?” Truthfully, if anyone asks me for a donation to some sort of charity, I usually throw a few dollars their way. I take part in work fundraisers, and although I don’t volunteer as much anymore, I get involved where I can. I’m not insensitive. I just think the way causes are done on Facebook are just a pile of crap.
I use Facebook for one reason only, to keep in touch with friends and family. Not to change my profile picture every week to bring “awareness” to some sort of cause. To be honest, most of the time when I see someone doing something cause-related to their profile picture, they don’t mention why, so the cause they are supposedly bringing awareness too is lost. But they look great with a green tint!
Here’s a video from Penn Jillette about this very thing. He’s quite vulgar (NSFW), but the message is simple. If you really want to help with a cause, do something real!
