Not saying that this is not true, but "World Socialist Website" is a website with content created to promote socialist agenda on behalf of a group of socialist parties.

Again, I'm not discrediting them, but it's good to know that there's an implicit bias and agenda on this type of content.

Same goes for the majority of the mainstream media. I wish someone would build a Chrome Extension that could reveal potential biases based on political donations, affiliations, and known shareholders, in relation to the media website you're visiting. It would add a lot of context and allow people to have more criteria to evaluate the media they consume.
