Think of it not as "please be rude to me, that's optimal".

Think of it as "I'd rather have the truth delivered rudely than a polite falsehood or slience."

You may say that's a false dichotomy — surely everyone should just tell the most informative truth and be polite. But this is often just too taxing, or not even possible depending on language and social skills. This is especially true on contentious topics.
