We like to hear people tell us what we want to hear, and it's been so long since with had folks like Rachel Maddow up there for good cheer. But if you're only getting your informationf rom Rachel, Ed, or any of the other folks up there, you're starving yourself of something very important: a mind of your own. As good as they might be at digging up important stuff, you need to be well informed on your own, so when Lawrence O'Donnell, or Al Sharpton are full of it, or when Ed Schultz or Chris Matthews don't know something, their error or ignorance doesn't become yours.
Yes, they are part of a corporate media. But that media is not necessarily part of this big conspiracy to conceal things from us. They are mercenary corporations in many ways, Disney paying for documentaries from Michael Moore that savage big corporations, MSNBC switching its line up from FOXNews Lite to FOXNews Antidote. They also publish a whole bunch of different newspapers, magazines, and websites over which all kinds of views are put forward. To indulge in paranoid rejection of information simply because it comes from a corporation is foolish. You'd soon starve.
What you need to do is look into straight news sites more often. You need to be reading about science and technology so when the time comes to debate it, or to gather supporters to you, you can add things to the discussion that might not have actually been there. In the long run, the success or failure of political ventures is strongly dependent on knowing the facts. The same goes for resistance to propaganda. If your notion is that you can somehow search out friendly enough sources, and by doing that free yourself from any potential misleading by your political enemies... well then you're committing the same error that FOXNews or Infowars, or any other viewers who flee from what they consider a conspiracy dominated media make. You're not analyzing the facts, you're analyzing who you're getting them from, and trusting or not trusting them based on that.
Don't begrudge yourself the fellowship of those who have views in common with you. But don't begrudge yourself, either, the opportunity to see the world for yourself, so that when you do talk with those who have common views with you, you have something more to say than "ditto".
