The hashtag campaign that was called #everydaysexism in anglo/worldwide Twitter in germany got an offshoot that was called #aufschrei (outcry). I've always found it weird that it got this/a special german hashtag because #everydaysexism is such easy language that most people understand it. I've just thought about why I have never felt as comfortable with the german "outcry". It is not just that it felt like a rip off - I guess that doesn't matter if it's for an important cause.
I think my problem is the shift in meaning:
#everydaysexism expresses: These things happen every day and you say nothing about it. These things happen every day and you look away. These things happen every day and are widely tolerated. Let's be more aware and courageous about this and call out sexism wherever we meet it.
Thus #everydaysexism turns the tweet into a tool of mobilization.
Whereas #aufschrei turns the tweet itself into an outcry. It expresses: "See which horrible things happen to us every day?" Which is okay, too. Visibility is a first step. But I found #everydaysexism more effective in being a call to take things out of Twitter.
