"I proved that..."
No, you didn't. Saying something isn't proving it.
"...perhaps even narcissistic..."
Calling even more names while justifying yourself for doing it before indeed 'doesn't bode well for a constructive debate.'
You're being an asshole, and if you're the face of Blurt! it's going nowhere.
And you're doing it again. You're taking everything personally. I've proven it, but since you claim there's a flaw in my statements, I'm curious that instead of exposing it, you focused on directing the conversation towards the supposedly imaginary "personal epithets" you're searching for :P This only proves that you've run out of arguments and are now engaging in pointless pursuits of alleged insults against you that never happened. Why? It's simple: you're distracting from a topic that's beyond you and engaging in verbal manipulation, a clumsy attempt to discredit your interlocutor in the eyes of others, trying to divert attention from the strength of his arguments to what you portray as his lack of civility.
That's what narcissists often do ;)
