You'd start reading and even before finishing a second sentence you'd realize - the person has no clue what they're talking about. Listen, Clojure is not a small language like Lua - you probably won't be able to form an educated opinion about it by trying to build something simple over a weekend.
People would say the hate JVM, when they actually mean "Java". In 3 years of using Clojure I almost never had to even read Java code. They'd dismiss the language immediately because it is not statically typed. If you think maintainers of the language have no clue about type theory and completely unaware of all the research of recent years happening in Racket, Haskell, Julia, Agda and Idris - you are very wrong. Things you can do with clojure.spec are absolutely mind-blowing.
If you claim that it's hard to find a Clojure job - that's not true. It is not harder than finding a job in Scala, OCaml, Erlang, Haskell or F#. If you've forced yourself to "love" Javascript, Python, Java or Typescript simply because they can guarantee an employment - I'm truly sorry for you. Sometimes I think people must be either crazy or completely ignorant - who in the right mind would choose JSX over Hiccup and Json over EDN?
If you claim that it is hard to hire Clojure developers - that not true either, you simply need to be ready to pay more. People come to Clojure out of curiosity - not for dogma, not for points in résumé. Clojuristas are usually more experienced devs, tired of all the bullshit that inevitably gets accumulated overtime in almost every language. Clojure(script) is not a silver bullet either. But in most-cases it simply makes sense and it just works.
