Well, I do think that honest people can disagree in good faith over complicated topics, like how to run the economy, or how much of a problem global warming is, or what to do about illegal immigration. So how about some simple, unambiguous fact that should submit to easy verification? As of late last year, about 42% of Republicans polled disagreed with the assertion that Obama was born in the US, while only 27% of Republicans agreed [1]. Plus the fact that our current sitting president was instrumental in formulating and then popularizing this lie. I submit this to you as a good example of 'know-nothingism' -- if there's some piece of information that challenges your world view, then you will do your damned best to know nothing about it.
