I want to answer in a very different direction to where most others have gone. To me it feels like people want to change bird names because the is not dangerous to them, while if they changed something that actually matters, it might upset some of their friends, people they go to church with, etc.
It would be better to start doing things that actually matter:
Figure out who in politics would be willing and able to actually change something and start voting for them
Figure out if your church is filled with anti-diversity people and leave it if that is the case
Work on making hires in your organization welcoming to people of diversity
Etc.
Finally, I see nothing in the description of McCown that should make him a target for renaming, as it is argued in a previous post.
