Hadn't seen this thread before but:
The answer to the OP is: because it's not all about you.
In other words, you don't have the right to define what an "audiophile" is and constrict the hobby to an attitude similar to your own. That's the type of solipsistic
view one often sees in audio forums, where some portion simply presume, for instance, that "the ONLY way to truly evaluate the claim of any audio gear is by personally listening to the gear." And that therefore an other person in to audio who may differ from that view is "Not An Audiophile." They are "Intruders!" And if they happen to be skeptical of a claim, simply stating this opinion amounts to "muckraking and trolling."
No. Not every audiophile has exactly the same beliefs or approach to audio.
An audiophile who owns a nice system but who, for instance, is skeptical of claims about $1,000 Ethernet cables, is just as much an audiophile, and has just as much right to express that opinion as the one who goes on about how transformative that cable was in his system.
So the advice is: Stop making it all about you. Don't assume your approach is the only approach and that alternative opinions disbar someone from the hobby or participating in public forums about audio gear.
