Renaming the airport honoring Inouye is bad move for two reasons: 
1) no government facility should ever be named after a politician. These people were paid to do a good job; anything less is unacceptable. They certainly should not be idolized in perpetuity. 
2) the use of Hawaiian names for all public facilities should be mandatory. This is Hawaii. Honoring native Hawaiians is the least we can do for what was taken from them.
