Haigh diagram
In materials science and fatigue, the Goodman relation is an equation used to quantify the interaction of mean and alternating stresses on the fatigue life of a material.
A Goodman diagram, sometimes called a Haigh diagram or a Haigh-Soderberg diagram, is a graph of (linear) mean stress vs. (linear) alternating stress, showing when the material fails at some given number of cycles.
A scatterplot of experimental data shown on such a plot can often be approximated by a parabola known as the Gerber line, which can in turn be (conservatively) approximated by a straight line called the Goodman line.

Wherever your line is for what's acceptable speech about Jews, Berlin's statements and attitude were over the line and have done great damage to the cause of ending the siege of Gaza and working towards justice in Israel/Palestine.
