I see your argument and I agree, but I just believe that with these talented/intelligent/passionate (valuable imo) people it's better to dedicate their limited valuable time to things they exceed at, not time for them to "correct" their sometimes ignorant opinions. We can ignore their ignorance, we can't replace their value.
When getting people to "correct" their opinions, my opinion is that they're far more likely to learn to mask their opinions, having to be constantly conscious of how others will respond to what they're saying and reducing their work throughput in the process.
