I did the activism. I did the walk so I'm going to talk the talk here.
The problem is only an utterly microscopic number of people will actually do anything. A larger proportion will, to some degree inform themselves of the issue but still do nothing. An even larger number will simply complain on a forum and call for other people to get stuff done but do nothing (looking at you@irusensei).
It takes a remarkably small number of people to make a difference, but IRL the number who will do something is even smaller so nothing happens. Those that do, like me, end up exhausted and despairing, feeling we've wasted a fair chunk of our lives, and had there been just a few other people willing to involve themselves things might be different, but that didn't happen.
If you want change it's there for the taking. But you won't.
