Music is subjective so you will enjoy Jazz if you like it and that's really all there is in my opinion. But then again, I don't think you should look at Jazz as one big pile that you have to entirely enjoy or not at all. This statement applies to all genres. Metal is cool but some artists just don't resonate with me and so on and so forth. I get it, Jazz has been put on a pedestal and when you go in music school, it's often one of the first course presented. But I have to disagree with your statement that Jazz is neither there to be enjoyed or hated because there's a lot of people who genuinely love (and hate) Jazz. So i'm gonna go on a wild assumption, and correct me if I'm wrong, that perhaps you just don't connect with the jazz you are exposing yourself to.
At the end of the day, I'm of a belief that life is too short to force yourself to enjoy something that just doesn't resonate with you. Doesn't mean that you can't give it a try, on the contrary. It's good to try. But if you sit there and you feel bored by what you listen, doesn't matter if all the critics in the world says that it's the best thing ever, to you it's just not enjoyable and that is completely fine.
And also, your taste will change as you grow up and change as well. So for a minute there, a type or genre of music might not resonate with you and 5 years later, you find yourself enjoying it. Reversely, there are things we enjoy when young and later on, it just doesn't resonate with us anymore.
In conclusion, enjoy jazz or even music in general however you want. Yeah you can hear what your idol or whoever has to say about how to enjoy this or that but it's not because it's true for them that it's gonna be true for you. In short, if you really want to develop yourself, go look for what resonates with you and what attracts you. Allow your taste to naturally evolve as you discover pieces of music there and there and most importantly, in my opinion, be yourself and enjoy whatever you enjoy!
