I’m not entirely sure why changing Lara Croft’s looks to have shorter hair would be necessarily a negative thing. It wouldn’t affect her character or her character arc.

I acknowledge that there is some reason to be cautious about character revisions, especially because there have been several recent instances where the designer makes changes without understanding why the character are the way they are, and they ruin the character’s personal arc as a result. But to say that all changes are SJW seems reductive and it also, frankly, seems to not describe the actual issue at all
