The answer is yes, Wikipedia is specifically a place where the worst biases can flourish. It only takes a couple of cranks to keep the biases in, and there are more than enough cranks around. I don't know that it can be fixed. The good news, though, is that there's enough transparency to in most cases make it clear to the careful observer what's going on. On any politically-sensitive topic, the experienced wikipedia user eventually learns that you need to check the talk page and see what points of view are being deliberately and actively excluded from the main page. Checking the page history helps too - bad pages tend to have a lot of reverts with angry check-in comments.
