Unambiguous definitions do not exist outside of mathematics. Furthermore, modern fascist communication strategies rely on existing within this ambiguity.
Should people be permitted to use the word "marijuana" on YouTube? See: https://www.youtube.com/watch?v=igtLqhX4BCA
Should people be permitted to use the "okay" gesture in videos? See: https://www.youtube.com/watch?v=lwJgr-4j14E
Should people be permitted to use a swastika in videos? See: https://en.wikipedia.org/wiki/Swastika#Contemporary_use
It seems the fascists are already taking advantage of the ambiguity.
