Really, what's the point? It seems a little heavy-handed and discouraging to new users, and doesn't add / change anything for search engine results of the question. Non-native English speakers, dyslexics etc may be really offended by it. Can it be toned down please.
The Stack Exchange system is built around peer editing. Everyone is encouraged to correct mistakes when they see them. If they have the editing privilege, they should use it to correct what's wrong. If not, they're encouraged to suggest an edit.
It's not offensive, and it's not meant to be at all. It's simply the community helping you make your post better. And through doing that, they help make the site as a whole better. This is exactly how it's supposed to work.
If you can bring up a specific case of this being offensive to you, then we can talk more specifically.
