Because a sane CoC does not allow personal insult or discrimination, period. No matter against who or in which form. It's up to the people to which it is applied to to feel if something fits the case; a rule in broad terms allows for both interpretation and a larger spectrum of application. Very specific and ultra detailed cases are wanted by the current wave of social justice warriors who just want a way to feel offended and vindictive towards whole communities, trying to sink their members. Notice as an example how state laws are general and encompassing. "don't murder parents of three kids" is already included in "don't commit murder".
