There's no one being attacked here. No one's being objectionally rude. It's just an exchange of ideas and viewpoints. Let those be.
Also – since these are just opinions, they are worth equally much. The truth isn't something you or anyone else owns. And what do you mean, 'deserves.'
This isn't trolling. This person is arguing, is what I think. Arguing civilly which is what this is, should be possible out here in the boonies (whith which I mean HN, in the most amical way).
If a "civil" argument is designed to mislead and intended to make the conversation incomprehensible, can it be anything other than a troll? This is a trolling tactic and has been forever. Look up "forum sliding", for another fun explanation of one of the tactics hyperliner is using.
Wrong. Not all opinions are worth the same. An opinion that runs contrary to established case law, for instance, is worth almost nothing.
"This isn't trolling."
Considering they've posted the same thing over and over again, it's pretty clear there was trolling.
