The easiest way to find out whether something should be changed is to try to apply a strict definition to it. It does not have to be a particular definition - any one will do.
A prime example of this is the word "justice". As soon as you put any kind of definition at all to it, you will suddenly find that a great many instances in your lifeworld are in fact not just. Not by any feat of magic, but by a feat of definition - suddenly, you find yourself having a yardstick able to measure just about anything. Including long standing traditional institutions that have been around since time immemorial.
If this is taking a radical stance, then being radical is the easiest thing in the world.
