When you tell someone "You still don’t get it",

When you tell someone "You still don’t get it", do you know the message that you are sending to them? you are sending a disrespectful message. It is saying that i am a slow learner or an idiot. The rest of your message was a well defined paragraph of very important information, but the beginning will make a person fume. I am not criticizing you, am just telling you its very important what you say and how you say it....the same that you advise the very important high profile person to do....
