I think it's important to identify a pattern. Totally get what people are saying that they attack "random" women, but there's nothing random about these targets in my eyes. They always represent progressive values. And, as you can surely guess, progress is fucking scary to a huge swath of people who will be left behind if they don't adapt.
In my opinion, it takes courage to represent new ideas and give a voice to those who barely have one; feminism, healthy body image, mental disabilities, etc. Conversely, it is cowardly to hide behind some false stories (and often also anonymity) to try and defame these same people.
