> There is no “both sides” here
If there's ever a disagreement or debate about anything, then there are literally always two sides.
You might disagree that the thing that the other side is prioritizing is as important (e.g. the lives of fetuses vs. the right to bodily autonomy for women), or that the thing the other side believes is even right (e.g. people who believe in racial hierarchies and other literally racist ideologies), but that doesn't detract from the fact that two sides do, in reality, exist.
In my experience, it's way more effective determining the thing that the other side cares about, then finding common ground if that's something that you also care about -- from there, it's a lot easier to make the case that while both priorities are good, your priorities might be more justifiable.
Shutting down the other side by saying their viewpoint is invalid has been productive for me literally zero times in my life.
(On the topic, this was a thing that Pope Francis was exceptionally good at: he actually listened to the concerns of people and spoke with them where they were at, even those who he vehemently disagreed with).
