I'm mostly learning Hebrew because I want to control my obsession with Jewish people. Some people tell me that it's a waste of time. They said it's better for me to learn Arabic. I tried asking people on other sites, but they just gave me non answers.
Assuming that it doesn't interfere with your physical wellbeing or social obligations, it's ok to have an obsession.
It would also be inoffensive to learn Swahili, Korean, or Akkadian. People do take interests in foreign cultures, such as Egypt-ophiles or Japan-ophiles, but it's considered an obscure hobby, outside of a shared community of interest.
In Israel, you may want to speak Arabic, for the same reason you might want to learn Spanish, in the US. Even though it is not spoken officially, it is still regarded as a language of commerce -- in other words, among laborers, or in the marketplace.
Consider that it's taken your entire lifetime to speak your native language as well as you do now. This will also require a considerable effort on behalf of your language teacher, who may want to know your purposes in learning the language. (There's a running joke about the otaku, who only wants to learn Japanese, so he can enjoy cartoons.)
May I ask whether you are Jewish, or mainly interested in Judaism? You're not particularly accountable to me. So, I am only asking out of idle curiosity.
