You remember learning that the reason veins can appear blue is cause deoxygenated blood turns blue? Well that's total horseshit. Your blood doesn't turn blue, and the reason your veins might look that way is because blue and red light travel though skin with different levels of success, so what's reflected back is a more bluish color. If you just learned this, you may be intrigued by these people who learned basic stuff way too late. Anyway, this dad asked if he was wrong for being really persistent with a teacher teaching the wrong thing.

    Text - r/AmItheAsshole Posted by u/mcweeden 4 days ago AITA for confronting my kids private school teacher about blue blood? Not the A-hole So this happened about a year ago but I'm curious. My wife said I drug it out too far and was an asshole. So my kid comes homes from school telling me he learned something new at school, and he was excited. So I was excited too and asked him what. He said "we learned our blood is blue today!" I felt a little bad but said to him "you know I was told that as a

My kid even said he believes his teacher. So I show my son more proof that I am right, but he is still skeptical. The next day I compose a nice email, not rude. Simply stating I told my son we didn't have blue blood and he told me that you told him I am incorrect. I give him some links showing we don't have blue blood. He emails me

    Text - So I email the teacher again and ask him if he can provide me evidence that he is correct because I cannot produce anything showing he is correct. He finally relents and says I must be right. But at this point, I now need him to tell my son he was incorrect so my son will believe me. My wife asked me to please stop but I didn't. I emailed him asking him to please tell my son and the classroom that he was incorrect so they don't go through life with incorrect information. He did tell the k

    Text - Now I feel that I have taught my son a few good lessons. A) it's ok to question things including those authorities B) it's ok to stand behind what your beliefs are especially with evidence C) it's ok to be wrong(the teacher) we can all be wrong, but when presented with proof, it's ok to change your opinion based on evidence. Was I an asshole for dragging it out?

    Text - materialisticDUCK Certi... 11.9k points 4 days ago NTA I say this specifically because the teacher should have taken a second look at his information the first time you told him that it was incorrect rather than doubling down. A good teacher would realize that they don't have expertise in a specific field (since knowing that your blood isn't blue is pretty common knowledge) and would have done extra research to find the truth Frankly, I think you did a great job doing what you did.

How did that teacher get that far in life and a degree in teaching and not know humans have green blood, not blue. No but seriously I don't understand why he thought that. It could be viewed as somewhat childish to go so far as to drag it out but at he same time the teacher is telling these students stupidly wrong information and it could make a fool out of them if they said they had blue blood.
