No. SO absolutely can be opinionated about what constitutes a good and a bad answer. SO's job is to get to the right and most helpful answer fast. You can't always rely on the community to root out bad actors.
The mechanism that SO uses for sorting answers is community votes. That poor or incorrect answers get up votes is a problem. SO only has its community to do that sorting. The corporate and diamond mods have specifically stepped away from doing this except in the most egregious and disruptive cases.
