Yes.Do I have to explain why it's smart to wash your hands after taking a shit? Some things are self evident. Also, vegans don'e shit.
That's the exact problem I have been talking about for years now. People have lost the ability to discuss matters, and you take a tone that is "well if you don't get it, I'm not going to explain it to you" and it does nothing but ostracise people!!! I know you're making a comedic point, and it's funny. But on a serious note it is, in my eyes, it's also one of the cornerstones of a much more profound problem.
Talking to people like they should know better and not giving any reason why a misconception to be discarded does NOTHING to further the understanding of a subject. Hitchen's Razor everything, for your own sake as well, because it makes you look into why you hold things to be the way they are and the reasoning that got you there.
I mean, this is a perfect example. My misconception was pulled apart in <2mins with a quick single word search and read. What's it say that nobody could be bothered just backing up what they were saying and ripping that out by the roots in the first place? You think you're doing anyone a favour by assuming it's plainly obvious?
