I think this is a fair question. Do outdoorsy people into camping; sailors into boats; speedsters into sports cars and automobile racing; electronics people into amateur radio; firearms enthusiasts into target shooting; collectors into collecting art, stamps, bottles, daguerreotypes, coins, antique cameras; etc.; experience the contentiousness we audiophiles experience? In my personal experience -- with respect to my other hobbies -- my answer is "no."
But it might also be a misleading question.
In my personal experiences in this hobby the in-person, in-real-life experiences are monumentally more friendly and less contentious than some of the on-line experiences.
So maybe the issue is not audio hobbyists versus non-audio hobbyists; maybe the issue is on-line keyboard warrior-ism versus in-real-life interactions.
In fact most of us are happy posters - we share our experiences with great systems and great people. Most of us are fascinated with current possibilities of stereo and the diversity of approaches we can find in the hobby and the continuous improving, even in small evolutionary steps, of our systems. We are now able to understand our systems and the hobby better than ever, our knowledge sometimes being that we must accept that most aspects can't be fully understood, just empirically accepted or dogmatically denied.
However, I can understand that people who think that stereo sound reproduction has got a peak in sound quality long ago and current standards are inferior to those of the past find little convergence with the majority that feels that sound stereo sound reproduction has been improving continuously along the years and find great pleasure improving their systems.
BTW, I do not think that the source of passionate debate is not my equipement is better than yours - it is deeper than that. It is mostly my objective in sound reproduction is better than yours!
Edit - I wrote this post a few hours ago. Now find that I am just repeating some ideas that have posted meanwhile, consider it as a summary.
