This is one version of a broad category of highly elitist sentiments that is disturbingly common. They all take the form of underestimating a person's "intelligence" or "worth" based on that person's understanding of one aspect of one system, e.g. computer virus vectors ("only stupid people get viruses"), social engineering ("only stupid people fall for phone scams"), etc. It's poisonous, and pretty obviously immoral, but most of all, it's indicative of ignorance. Experience with people will demonstrate that this sentiment, even stripped of its hatefulness, just isn't factually true.

I think your comment is repugnant. We all have areas of our life where we can be a little naive. We, as a society, should work to protect the weakest among us - not blame them for their weaknesses.

If your problem is that these people aren't smart enough and shouldn't be voting, then a democracy probably isn't for you.

While that may or not be true, those individuals still have a right to vote. Whether you or I like it or not. Someone interfered with that right.
