Your personal attacks on me are actually proving my point. In your original post, you said:
"In the specific case of conservative politics, why does it matter that it's so skewed? I have absolutely no issue with, in this specific case, conservative politics not receiving much attention."
That's a form of censorship and manipulation, especially because Facebook is not seen as an editorialized news source, but rather as a representation of one's community. You seem to think it isn't censorship though:
"I am not sure how you are confusing me and facebook's curation system not giving attention to certain sources and positions based on their credibility and integrity with actively preventing people from speaking."
This had nothing to do with credibility or integrity. It was a group of people with a very specific political ideology that were subjectively picking news and having it appear in an organic feed, when it was really editorialized.
I'm not confusing you with Facebook's curation system. You're entitled to your opinion. I'm telling you why your opinion shouldn't be applied at scale (in this case, to a system that appears organic) and also why you should care about this not just for this one incident, but for the implications that this has on a larger scale.
So you don't care about conservative views getting silenced here. After all, conservatives are wrong, right? But what if the major media outlet changes it's mind and starts to think liberals are wrong, and thus silences liberal content? How will you feel then? This isn't about political ideologies. It's about the implications of an unprecedentedly large and trusted media outlet taking sides and deliberately influencing it's audience. Liberal or conservative, that's dangerous.
