Refuting someone’s core beliefs on facts is often perceived as a personal attack

Evidence

In politics, it is usually considered an ideal to argue hard on the merits but fair on a personal level. Given the psychological effects described in Sect. 2.​2 it can be extremely treacherous to follow this ideal in practice. The fact that one wants to distinguish between the factual level and the personal level, and possibly does so from a sober semantic point of view, does not mean that the addressee will understand it that way. If you want to refute a central conviction or even a set of beliefs of a person on a factual level, for example, you have to break through the person’s confirmation tendency and trigger a cognitive dissonance, which in many cases will be perceived as an attack on the person. If one criticizes such a belief not from a substantive but from an ethical point of view, the danger that this will be understood as a (fundamental) criticism of the person is even considerably greater. — Holm Gero Hümmler, Ulrike Schiesser, Fact and Prejudice, 223
