Respect be use that is the theme
Humans are a very social species who essentially require interaction between them and other humans. We form societies so that we can divvy up work and get a lot done, while also satisfying the part of us that requires interaction. This is why we've formed languages; so we can communicate with one another and come up with cultures and ideas.
An argument does not have to controversial: it just refers to someone taking a stand, arguing for or against something. It does not have to be in opposition to other people's ideas either.
So now we have two options left:
writing that takes a specific perspective
and
<span>writing to explain a writers ideas on a topic
I find both of them not perfect: I would rather say that an argument is a claim, or a statement, that needs to be supported. But from the two I think the better one is </span><span>writing to explain a writers ideas on a topic (this is the best answer I think) since a perspective can mean a "point of view" and this not what an argument is.</span>
