This is a good introduction to hate speech as a legal phenomenon, with emphasis on social media and college campuses. Exposed me to a lot of useful viewpoints.

As said by a colleague in response to this tweet.

all boys ritually emasculate/are emasculated by other boys as part of showing you are a real man. Trans women do not respond to this phenomenon the way that boys do and, as a result, are treated differently long before anyone realizes they are trans.
