In answer to the original question:
Perhaps because there are some trolls who seem to try and use these threads as bait to trap those who don"t share their love of horns:
https://forum.audiogon.com/discussions/why-not-horns?highlight=horns
Your first reply to that thread was:
I absolutely loathe horns!
Not exactly an inviting outset for further conversation on the subject, but nonetheless a clear statement on your stance. I don’t know whether the OP of linked thread (or others there) ever came to ask you this in earnest, but why, if you were to elaborate a bit, do you resent the sound of horns? I’m simply curious. Is it horn-hybrids in particular, or all-horns equally - perhaps even more? Are there aspects of horn sound that triggers your resentment more than others? Ever heard horn speakers (hybrids, all-horns?) that appealed to you more than to lead to the thought of simply hating on them?
You claim to provide an answer to @johnk, but still this hasn't happened. Why don't we start here?
