Earlier quoted context omitted.
Presumably for the same reason you wouldn’t get a civil rights activist to replace the captain in a Navy boat. We need people fighting for civil rights, but we also need to create room for people from diverse backgrounds to do all of the rest of the work that needs doing.
This is a really poor analogy. The position of captain of on a warship is almost entirely unlike that of a corporate board member and corporate board members often represent external interests.
Trying to show viewpoints in the clearest and most concise way, is the height of discourse.
Making a backdoor point by claiming "poor analogy" is basically noise on noise. It muddles both the original point and fails to make a coherent followup. Defining a different set of criteria for what to compare on, does not change the initial comparison in a meaningful way.
Define an interpretation (which may get clarified) to focus in on an objection, then form a second viewpoint.
