Technically not a slippery slope, just a false equivalency. Renaming a branch and rewriting a project in another language are in no way equivalent levels of effort, so comparing them based on the principle of "no skin off my back" the original poster articulated is disingenuous.
Saying that the two cases are not equivalent is a criticism of the level-of-effort comparison, not a criticism of a particular people-group's subjective suffering.
