Even if the post is true, it was the worst way to present it. It reads like trolling:
Call out people's politics with grandiose rhetoric, not backing up any claims with links to evidence.
Declare the other side is unbiased.
I mean, Internet 101 would dictate you downvote and disengage. It's not going to generate a discussion that would change minds or be constructive. Even now we're not talking about small website discoverability, but instead downvotes.
EDIT: I'm going to put my money where my mouth is. I'll try the same post.
