I am an unapologetic propagandist for defensive boxing. I think it's important to value defensive skills and promote them, both for the health of the individual fighters and for the health of the sport in a culture where there is growing awareness about head trauma.
But I wouldn't talk down to somebody who liked Led Zeppelin for failing to like Miles Davis. Led Zeppelin is one of my all-time favorites, to be honest. I could probably listen to just "Whole Lotta Love" at least three or four times a day for the rest of my life and not get sick of it.
But Led Zeppelin fans should be willing to consider that when it comes to achieving the pure sublime in music, Miles Davis is closer to getting the job done. And if you like Led Zeppelin, I think you have good taste and probably have the capacity to develop an appreciation for Miles Davis.
Learning enough about the technique of the two arts to enjoy jazz music or elite defensive boxing is a worthwhile pursuit. I recommend doing either to anybody with the free time, and would suggest locating some kind of legitimately knowledgeable teachers in both cases.
On the other hand, some people think Michael Bolton has achieved the most powerful levels of soulful vocal power in the history of music. Even though one assumes, at some point, these people have had the opportunity to hear the likes of Sam Cooke or Joe Cocker, as well.
That kind of taste is okay, too, I suppose. But if your approach is that lowbrow when it comes to fighting, then go ahead and skip over boxing. There are felony fights and tough-man-competition videos for you on YouTube.
