Just saw this thread now. My thoughts on the Ice Bucket Challenge: it's annoying, it's self-indulgent and a majority of people doing it on Facebook don't really give a shit about raising awareness and are more concerned about receiving social media validation. But on the other hand, it's definitely generated a ton of donations and awareness for a debilitating disease.
So I'm happy to deal with the nuisance of it, but I wouldn't take part in it myself because there's just something about it that rubs me the wrong way. It's different when people are actually donating, but I'm positive most of my friends aren't. And I also don't like that this challenge makes people like me become judgy about whether or not people are donating, because making a charitable donation shouldn't be something you feel pressured into doing.
