I stopped being opinionated when I realized that the vast majority of what I'd be opinionated about pretty much doesn't matter enough at all, or doesn't matter enough to get worked up about. It's an ego thing, and being serious about relatively mundane things is pretty fragile. Not that opinions in general are bad, but even if one is very well-informed, one choice over another often just isn't very significant.
Especially in code, if there's a reason to pick one style over another and it seems preferable, I'll say that, but if someone does something else it's probably pretty negligible, and any sensible opinion should change over time anyway.
If someone on my team was very opinionated, I'd think of it as immature. In a non-professional context, I might argue for the fun but that's it. I like back and forth more than black and white.
