There is a tumblr called Microaggressions which details those quiet little pings of bullshit that start to add up.
What is a microaggression? The best way to describe it is to say it is “death by a thousand papercuts.” It’s that stupid throwaway comment that makes you seethe inside, and if you yell about it, the person goes “What’s the big deal? It was just one stupid comment. Jeeze.”
“Are you ladies familiar with science fiction at all?”
[Said by] A man approaching me and my cousin. We were attending a science fiction convention, sitting in a members only area of the con, wearing our con membership badges, and playing a science fiction game. I was speechless. I had no idea how to answer such an absurd question.
