I don't think it is a fair question because most companies, teams, managers have some guidelines on how to go about this kind of thing. Some are written and unwritten.
I've worked at places where it was acceptable to pound your fist on the table until you get everyone to hear your point of view. Never give in. Never surrender. At other places, you'd be fired for doing that, so you just agree all the time. So how does my past experience help you when I answer this question?
You learn to wait and see how these debates are handled. People like to think they're upfront about this, "I don't want any 'yes' men on my team." except every time someone disagrees, they get yelled at without an rational reason why from management.
People have different temperaments and this question may let you know when someone tends to do, but there can be a lot of variability in different settings and circumstances.
It's difficult to tell people you prefer a certain type of behavior because they'll just alter their answer in hopes of getting the job. You can try it and see if you can tell who is bluffing or not, but that's pretty difficult most of the time.
If getting along with the team is so important, they should spend as much time as possible with job candidates. Hopefully, you can find the answer without asking the question. If someone thinks the question is too aggressive, they may not be a fit for your team either. I like being upfront, so aggressive would not be how I would describe this question.
