My advice now if you're curious about what Bannon thinks or what Breitbart really does is: don't start from a position that they're bad, don't believe the media frenzy, don't follow the line of reasoning of people you agree with, definitely don't assume they're neo-Nazis or white nationalists, don't go out looking for arguments one way or another. You just have to start at neutral and spend a ton of time reading Breitbart, listening to his radio episodes, reading what former Breitbart workers have to say, getting savvy to how the community thinks, and, if you can stomach it, using the anonymity of the internet to ingratiate yourself to online fascists until they open up. That's how I did it, anyway. Not sure I can actually recommend it.
Basically, I think I really would rather people did their own research and came to conclusions I might disagree with than listen to my arguments and evidence. Which is the sort of frustrating thing to say that leads people who want to be told what to think to conclude that everything I believe is bullshit. Oh well. Back to taking a break from writing/getting mad on the internet.
I think you've spent too much time hanging around thick-headed individuals. HN is not filled with the self-serving types of people you're describing. Commenters are eagerly awaiting support for your point of view, and you're practically spitting in their eye. No one will care what you have to say after that.
It's okay to not agree with an approach or argument you used before, or even the why of the existence of either. But it doesn't mean all of the content is useless.
