Wow, you are taking this way too personally. I never called anyone illiterate meaning that you can't read or write, which by the way has nothing to do with this topic.
I merely wanted to point out that when someone buys a radio and sees the words "Privacy Codes" They are more than likely going to expect their conversation to be private with whomever when it will not be. If we use the term "Filter codes", which is accurately describing what is going on here, there would be much less of this confusion.
If you do not want to be less confusing to newcomers that is your choice but I choose to be less confusing.
