Pacifism vs unintelligent

The idea that some people just don't want to put effort in explaining something, if it's seen as too much. The idea of walking away seems to make people think they're not intelligent. Not fighting, or being aggressive when the situation, point, subject seems. Unresponsive, not heard.

There is no point in hitting your head, or testing to make someone, or things see a point after while. Though this is apparently seen as not smart. Walking away, when or before something gets heated. This I don't understand
