You are correct. There are thousands of sources, but anyone with a brain can filter out the ones with extreme bias. Everyone knows that Drudge will slant the news one way, and the NYT will slant the other way, and both have also been known to make stuff up in order to fit their agendas. Therefore when reading these sources, this must be kept in mind
Critical analysis takes time and effort. I know that people are too lazy to do it (just look at the majority of people here), but it is necessary in order to fully understand world events. If you just blindly believe what you are told by the boob tube/political candidates/etc, then you are nothing more than a fool.
