When I have ranted about Java (thankfully, I don't do much Java development now, and we have Kotlin), I haven't intended to hurt anyone. I just want people to do better. Both in the sense of urging developers to be using better tools than Java, and also in the sense of urging the language designers to fix problems I perceive.

I tend to save my cruelty for those who have been actively trying to harm me. Which doesn't really happen, because I have a relatively placid life.
