I disagree and I will tell you why.... in a moment.
I agree that changing a profile picture was a silly idea. Changing the picture doesn't support or do all that much. So, if I agree with that, how do I disagree with it being a stupid thing to do?
I disagree when people say it did nothing. It spread awareness. It got people talking. For several days on my page, there were people sharing links with people who didn’t know ways to help. People giving out information for ways that other people can get involved and do something good. People relating stories to each other on their experiences. Bonding over something so terrible isn't the best way to bond but finding someone, be it someone already in your life or someone new, who understands and can relate to you? Someone you can openly talk comfortably with? That's a good thing. There were people sharing links and phone numbers for people who need to get help.
It got people talking about an issue that doesn't get talked about often. It got people sharing and reaching out to others. It got people who previously didn’t think about helping thinking about it and doing something more.
To me, all of that is something. It might not be much and I know not everyone had this going on between the people on their social network. I know I'm not the only one who saw something like this happening through their social network, though. I also know not everyone who were given links will do anything with them. I know not everyone will start finding a way to help. This goes with anything. Same as how not everyone who had the nerve to belittle the people changing their photos and telling them to find a real way to help will do something more other than complain about what other people aren't doing. If even a small percentage of people get involved and look for ways to help and do it, though? Good.
The premise of it might have been stupid but I disagree that it was all done for nothing. Spreading awareness and getting people talking and sharing is never useless or pointless, especially when it comes to subjects that people are generally less inclined to bring up and talk about.
