The line about protected classes is not in addition to a general rule against harassment, or emphasizing that kind of harassment in particular, it replaced that rule.
There is a separate rule against personal attacks, but is that rule supposed to take over harassment in general? That sort of makes sense in a vacuum, but then it leaves the exact meaning of the 'harassment against protected classes' rule kind of confusing. What does harassing a class mean exactly, and can you harass a non-protected class?
