We've all had experiences. All of us. But we don't really talk about it. From the man who tries to sneak a peek up a 15-year-old's skirt as he helps her climb onto a hay ride to go apple picking, to the tongue-wagging jerks who cat-call and intimidate a young woman on the street, then call her highly inappropriate names when she objects, to the very real differences in our perceptions of high-achieving women vs. high-achieving men in the workplace. Sexism still exists—even if most people are inherently good, and acting in a sexist way isn't always a conscious effort.
So kudos to Londoner Laura Bates for creating Everyday Sexism—a platform for women (and men) around the world to report their experiences with sexism. If it makes you uncomfortable to read these experiences from over 80,000 worldwide, then the site is doing it's job. In April 2014, Everyday Sexism was published as a book by Simon and Schuster.
The bottom line is, if you feel intimidated, or even just the slightest bit smaller than you were a moment before, whatever comment or gesture made you feel that way wasn't appropriate or normal, and that's worth acknowledging.
