I understood his last two sentences to mean that if one is skeptical, not to be antagonistic. Which I abided by.
Now, if the OP meant that ANY suggestion of skepticism was by nature "antagonistic" then that I think is unwarranted. There’s no reason differing views between mature adults should be rejected as "antagonistic" simply because "it’s different from what I believe, and I don’t want to have to deal with alternative viewpoints."
However, IF the OP had written something clear such as "This thread is based on the assumption after market AC cables can alter the sound of a system: if you are skeptical about this, please do not bring that to this thread, as I wish to discuss purely the ideas of how AC cables could alter the sound of a system. Thank you."
If it had been clear like that, I would completely understand and wouldn’t have entered this thread with another skeptical view of "why power cables affect sound."
Anyway....having made my case I'll refrain from posting more in this thread. (Unless possibly baited to, or unless someone is actually interested in my responding).
