The fascists are trying to kill people. In response your argument proposes what is best described as a kind of Stockholm syndrome. But instead of a empathy for captors your argument would have victims have empathy for their murderers. Like some kind of extreme form of rape culture. It's disgusting in my opinion.

Those tolerant people are feeling empathy for each other regardless of their group. They are even expressing empathy for Charlie Kirk's children. So they are following the social contract where as the fascists are not.

Fascists want to kill out groups. Fascists are practicing parochial empathy if even that. Your argument seems to have no grasp of what empathy is or how to practice it in a healthy or useful way so it is not compelling. edit: typo
