[For some reason, the idea of Akane working alongside other people, people Ranma's never known (or had even tried to know, but- that wasn't the point), bugs him. So he scowls at her, staying right where he is, unmoving in both his position before her and his stand in the argument.]
That still ain't enough, Akane! You don't know what you're goin' up against!!
[It's such a weak argument, especially for someone like Ranma who goes charging headlong into any fight without a second thought. In his mind, of course, it's only not a good idea when it's Akane doing it.]
