I agree that it's worth scrutinizing your own arguments and try to be conscious of biases. I also agree that we all often do a lousy job at it. That said, I am generally open to arguments and I feel that I do at least sometimes change my mind when convinced by reasonable arguments. But that doesn't at all imply that I should stop believing something just because a handful of people think they need to shout something at me. And the argument "there might be other, silent people also disagreeing" goes both ways, there might be other people who agree with me but choose to remain silent too, and that are uncomfortable with what the other side is claiming.
