Java is just a programming tool and, while I would have preferred to use C++14 for all my Android projects, it is what it is (NDK make sense only for heavy duty applications).
Now, imagine for a second that you are a junior programmer, that only knows Java. You've heard of this thing called Clojure and you want to read and learn more about it. What would you think if someone called you brainwashed just because you only know Java ? For most people this means EOD (end of discussion). Calling someone brainwashed just because he doesn't have your level of expertise with other languages will just make it ignore the good parts of your comment.
In the end it is about what is more important to you: vent some steam about how much you hate Java or guide someone to learn more about a Lisp language.
Not so long ago a student of a good school in US would know Scheme and C, not Java or Python, and the move to Java as the language for teaching CS is, in my opinion, the result of the same regrettable process of brainwashing.
btw, I never talk Java issues in a context of a personally, only in a broader sense of a "social phenomena" partly explained by well studied "effects" in social psychology.
Unfortunately, Clojure will not be suitable for Android development in observable future exactly because "Java" cannot fulfill its promises - Clojure's runtime is "too heavy and too slow" (too wasteful) to run even on a newest smartphone hardware, and in this, again, so-called reality re-asserted itself.
