There are mos def some who don't ask enough questions. Whether it's hubris -- which I suspect is extremely common -- or the desire to not, as I said, look stupid.
For myself, no, I don't want to be thought of as dumb. But also, I don't want to look like I'm just in search of someone telling me WHAT to think if I were to ask them what THEY think. But I do like to ask people what they think, esp. if I suspect I'm likely to not agree with them. I don't get a whole lot from protests and people waving their signs. I don't desire to dwell in confrontation, but nor do I desire to dwell in an echo chamber.
