#DistractinglySexist or #DistractinglySexy?

This is a news clipping that highlights a photo exhibit inspired by a PhD candidate of psychology, Eden Hennessy. She plays off of a Nobel Peace Prize winners statement that women in the laboratory actually harm science and create a disruption in science. I don't think it's necessary to critique Hunt's disparaging words right now because it's obvious he's a an highly accomplished, educated imbecile. However, I find it striking that the hash tag created off of his words: #distractinglysexy was a pun created by women in response to his remarks. Now, Hennessey is criticizing Hunt with her new exposition of gender discrimination in science. But why wasn't #distractinglysexist the first response from Twitter? Why did it initially become a joke with #distractinglysexy and not #distractinglysexist? Additionally, why is everything now a hash tag? Do hash tags give social justice issues more power, more of a credible voice? Or does it just speak to our constant use of social media in nearly everything we do these days?  I would definitely check out both articles:
