Why is it said that political stance should not be the only standard for interpersonal relationships? Because when a society begins to get used to "judging people by their stance first," the relationship between people will gradually degrade from understanding to camp identification. Political stance can of course serve as a filter because it indeed reflects a person's understanding of order, fairness, power, and freedom, and also influences whether they can walk together for the long term. In reality, people with vastly different values often find it difficult to truly get along deeply.

But the problem is that many people later elevate "stance filtering" to "judging character." As if just having a different stance means that person must be stupid, cold-blooded, evil, or not worth engaging with. As a result, people are no longer seen as complex individuals but are compressed into a political label.
In reality, some with radical views are sincere in their dealings; others with correct slogans are extremely indifferent to those around them. Political stance can reveal part of a person's worldview, but it can never fully explain a person's entire humanity.
Truly mature people will acknowledge the existence of stance differences and use them to judge whether they are suitable to walk together; but they will not therefore completely lose the ability to understand others.
Because once all relationships are taken over by ideology, what remains between people is no longer communication, but only enemy and friend recognition.
