It's not the culture of anti-competence (although, yes, that exists).
How many times have you tried to communicate a novel idea to competent people just to have them dismiss it with obvious problems that clearly don't apply to your idea? That doesn't happen because they can't evaluate your idea, it happens because they don't understand the idea itself.
When the innovation is small you can get away by repeating it again and again. At some point people stop, take your idea into account, and suddenly understand why none of what they said applies. But when it is something too different, you can't do this one either.
