1. naming rules almost always lead to verbose inelegant names that humans would not really use at some point. (I said almost to ward off a war)

2. The part of CSS that I am generally better at than most developers is specifically in understanding the cascade. BEM, in order to help the people who are not good at the part that I am good at, pretty much makes it impossible to use what I am good at. I feel like I'm being Harrison Bergeroned every time I use BEM. But also the names I have to give things rankle.
