I knew that's where you were going. I knew it.
I said nothing of the sort about the validity of his statements. I did not engage in an ad hominem (i.e. Vaxry is an asshole, therefore he's wrong). I did not imply that it was easy to make a compositor. You were the one that read all those things into my statement and took umbrage on his behalf.
I implied it sounded like complaining, specifically about other people simply existing and having hobbies that intersect with his own. If his opening salvo is "almost all the other compositors suck beyond opening terminal windows," on a blog post titled, "We don't need more Wayland compositors," I'm not required to be interested in what sounds like hyperbolic criticism.
And since that choice is based on my entirely subjective assessment, I'm not required to justify shit.
You seem to be under the impression that I'm obligated to take every claim and see if it's backed up by evidence.
I'm not, and I don't feel any compulsion to find out if Vaxry has made rational claims or not. That's the beauty of using subjective reasoning; it's not reasonable for anyone but the subject (me).
Be my guest and see if he's justified. Tell other people. I stopped caring what he has to say here the minute I read that paragraph, and I choose not to hear him out any further either way.
