(edit: I genuinely don't understand how your replies are anything other than ad hominem attacks. Your responses are about as effective as a toddler asking "why?" over and over and over again. Either deliver a substantive counter argument or stop replying.)
(edit 2: I assume you are the one who downvoted this reply. That only adds to the factual evidence that you are struggling to defend your position via legitimate means. This isn't a personal attack. I hoped you would engage in legitimate discourse. Please do better in the future.)
Downvoting can also mean that the downvoter doesn't think it's worth the time to engage with prose. It's a bit arrogant to assume that a downvote means someone can't come up with a cogent argument against you; the fact that you make that assumption points even more strongly at the idea that it's not worth arguing with you.
I would say that classifying an argument as "silly" without any supporting evidence is borderline ad hominem because it doesn't make a substantive critique of the assertion, and instead colors the character of the opposition. But that shouldn't take away from your position.
As for your suggestion that I am being arrogant, I can see where you're coming from but I also feel as though I'm within the bounds of fairness to push for a reasoned response (instead of an emotional appeal).
All that said, thanks for replying in a way that advances the discourse. Much appreciated.
