As someone who is extremely rational and unemotional, let me tell you that being like that sucks. It's like living life outside a window. It's not a point of pride, at all.

And these chuds are just classic examples of garbage in, garbage out. Yes, if your premises start skewed, and you're unable to recognize that you even might be biased, you're gonna come to some pretty ironclad (wrong) conclusions.

Another bad sign is that they think they can apply their "logic" to every situation. I absolutely am aware I can't, so I try very hard to not engage with subjects I'm unfamiliar with.
