Earlier quoted context omitted.
Master is used in many context like master key, mastering a song, master copy, having mastery in something. To stir up controversy because one interpretation is "problematic" just emphasizes that interpretation and reminds everybody that they're not suffering from enough guilt about past events they had no personal involvement in.
That logic always seems to fall apart for me. Of course words have had different non-problematic uses over time, before and after a problematic usage. But that doesn't negate the fact that it does and did have a problematic usage. White people who want the ability to say the n-word often use a similar argument. ("It's only problematic [when/if]...") .
I believe the movement to alter what words we’re allowed to say in our vocabulary is lead by educated mostly white “allies”. These people don’t speak for the underprivileged, they’re creating ways to feel better about themselves through self-policing because they don’t have any real idea about how to solve the issues that actually affect people.
