Complain if you must, but there is a serious point involved. People get invested in technology and they start to adopt certain patterns of argument that stem more from their own investment than anything else. I tried to highlight the pattern using humor. Nothing personal intended.
In real life I do dislike java and try hard to avoid having to use it, precisely for the reasons highlighted in the OP. I do like Haskell, and many other things. Note: all the real Haskellers are nice and would never be as snarky as I was.
Your way ends conversation and attempts to belittle, my way makes the point in a way that allows for discussion.
