There will always be conflict. I'm currently working with two of the nicest people I've ever met but we still have conflict and we still argue and 'fight' over big things such as direction of the company, goals for growth, etc.
It's a matter of how you fight - with these guys it's respectful arguing, sometimes raised voices, even talking over each other, but I know in the end that they're fair and we respect each other.
In my previous company I worked with one of scummiest people I've ever met and the fighting was quite different. He avoided it rather than addressed it, and he also seemed to take my disagreements personal. But from the outside it probably looked like he's 'nicer' than my current partners.
Heated arguments are not a sign of "not being nice", they're just a sign of differing opinions. If having a different opinion makes it impossible for you to "be nice", then you're not nice.
