Censorship occurs in the politics stream, too, believe it or not.
1. De jure censorship: Imgflip will censor the most extreme/violent political content, because the site mods here have higher standards than extremist havens like 8Chan and Stormfront and Parler and Gab.
2. De facto censorship: Liberal opinions are hard to spot on the politics stream because liberal memes *never* make front-page no matter how clever, articulate, or factual, due to the biases of this stream’s user-base. Liberal comments are frequently downvoted to oblivion and always trolled. And even searching politics memes by “New” isn’t a great way of finding liberal content because the stream is every day cluttered with off-topic Minecraft and homework memes for mysterious reasons.
Ergo, PoliticsTOO exists as a stream on Imgflip where liberal opinions can actually be seen and heard.
Worth noting that explicitly right-wing streams like conservatives and FirearmFriendly exist, and they practice their own PoliticsTOO-like non-viewpoint-neutral moderation strategy.
Also worth noting that I mod political streams that have no stated viewpoint, such as Politics_Redux where right-wing memes will be featured if submitted.
