Everyone, including debaters, should be sensitive about the use of language that many find offensive. Bringing these feelings of offense into the open is helpful. I am uncomfortable, however, when these issues become formalized in a debate round. There is often dispute about what exactly was said, with no official recording. Some of this language use is more intentional than other.
Some language is more inherently hateful than others.
More serious violations will be addressed through speaker point deductions. It would take a very egregious and clearly intentional language violation for me to feel comfortable voting on it.
