wjlesaulnier Of course not. We try to have icons for a wide range of topics. We also have icons for rape, nazis, bullying, etc. That does not mean we support it in any way. We have many teachers as users, for example, and they need to communicate sensitive topics. If a teacher talks about nazism, she might need a symbol for a presentation for her class. Neither us nor the teacher supports nazism by doing that.
We do have a lot of internal discussion about where we draw the line. We have implemented a filter that removes any explicit content to feel safe while searching for icons. We are always open to hearing good arguments for and against certain types of content.
