I mean I think that's great. Fair discussion in good faith should always be welcomed.
The problem is when debates in bad faith or based on non-factual information happen.
Consider COVID, which god knows why became politicized - where one side supported taking basic precautions in the form of wearing masks, hygiene, distancing, and getting vaccinated, while other side did not.
Scientific and medical consensus was nearly unanimous in supporting the former - the two sides of this discussion were not factually equal. One side was working off of false information.
In this case trying to foster "balanced" discussion just ends up supporting the spread of misinformation.
This is what the poster who said that "reasonable people can’t differ on everything."
There are things where it's ok for everyone to agree on. It's not always a sign of some algorithmic conspiracy to force an echo chamber.
