You're right, sorry, this was just... a buildup of frustration with him coming to a head.
I presume you've been reading posts I made on other forums which makes sense for the sudden jab and unexpected outburst. You do realize posts are independent from each other, right? So don't go subjugating yourself and projecting onto others your negative biases that you have come to cultivate. Unfair to new posts and rude to passionate posters when you unwarrantedly spit venom at them thinking you're doing everyone a favor by exposing them especially in a forum that has had no drama as of late or at all.
Also, why should anyone apologize when they did literally nothing wrong to you, yet you react to them with an attack? Sounds like a you problem, something a specific creator must realize after dragging a whole community down with them...
