Sure, I'd go one step further too. If you've been kind and the person took offense anyway... don't just move on, avoid self-flagellation as well.

Some people only receive straightforward truth that shouts in their face. Otherwise they find a hundred of excuses to slip through any kind argument. I agree that brutality should not be default - it’s simply statistically non-beneficial to your self. But avoiding it at all costs make you and/or your circle pay these costs eventually.

One of the human types may be called “emotional extremist”. They push borders until someone explodes in their face, and this is the feedback they use. Not reality or arguments. Cold controlled unkindness that presses them against the wall is much better in this case because otherwise someone will be driven crazy by them.
