The only way things improve is by dragging them out in the open. If we just ignore the problem or stop discussing it, it just continues to grow and get worse. I'm sure plenty of people in the '60s didn't want to talk about racism either. People 20 years ago didn't want to discuss homophobia. While those problems still exist, you bet your ass they have been lessened due to public discourse and the media. Most kids growing up today don't see anything wrong with dating someone of another race, or having a friend who happens to find the same sex attractive. That's partly because people talked about it and didn't just "shut up" because it made people uncomfortable.
I may be the only person in the world with this opinion, but I really enjoyed Leigh's infamous appearance on the E3 Bombcast! By contrast, I found the Mega 64 guys to be far more annoying, and much less entertaining. Opinions, eh?
I bet this hashtag movement will be remember for the end of time! Or like... for two weeks. If you want to change something, then stop posting fucking messages on the internet and actually do something about it.
As someone already pointed out, raising awareness for an issue is definitely considered to be "doing something"
