This is a very dangerous argument because it infringes the democratic base itself.
It's not necessary wrong, but be careful because with the very same logic you could argue the people don't really know what they want, they aren't able to govern themselves, we, enlightened creatures, should decide the way forward.
Again, it's not necessary false, but it leads to authoritarian and paternalistic consequences
What do you mean? He's just a very polite fluffball
