Vegetarians are dumb. Meat is needed for healthy brain development.

Katherine Ortiz April 3, 2013 - 4:53 AM

I wouldn't consider myself dumb, but thanks for your wonderful "insight."

Katherine Ortiz April 3, 2013 - 4:57 AM

That's insanely rude of you to say, but I don't blame you because we live in a culture where we can hide behind a computer screen and judge people based off of their looks. I'm sure she can care less if you don't like the way she sounds or looks. These videos are about science, it's not a beauty contest. So leave your negative comments about her looks out of it!

We aren't going anywhere. :)

People in this day and age hide behind computers to say negative things, such as you did. I say this because IT IS rude. You wouldn't normally go up to someone in person and say those things.

Example B: "reading comprehension failure" and "pine cone up your ass." Two things you wouldn't and shouldn't say to someone.
I hope getting those negative remarks helped you in some form or way. :) Have a nice day!

The entire comment was a build up to this: "Why do we randomly dislike some people for no apparent reason? Are we just hotwired to not like certain types of people or what?"

If you can't grasp that then I'm sorry, but that's a problem on your end, not mine.

It's an issue related to Psychology and it was the easiest way to explain it. I have an MD/PhD in Biological and Biomedical Sciences. I'm a Geneticist, a Scientist. And as a Scientist, I think it's a very interesting question.

I meant on an evolutionary scale.

at least I tryed, next on the list of options – start shooting you herbavores

Katherine Ortiz April 5, 2013 - 11:11 AM

If you have the audacity to insult someone, please, for the love of God, learn how to spell.

tried* herbivores*

You're ignorant. Vegetarians are humans, just like you. Just because we have different lifestyles doesn't mean you should "shoot" us. I don't have anything against omnivores.

Wow, do people not have a sense of humour any more? You reduced this guy to having to say 'it was a joke' in an apologetic tone in order to please your annoying sense of self-righteousness. Seriously, nobody cares if you're offended about jokes on vegetarianism.

TheYokiMoki June 6, 2013 - 9:18 PM

im pretty sure we all know it was a joke its just that people in the comments like to argue

WesOfX August 24, 2013 - 1:34 PM

The men thought of mechanical objects when they heard "Spring"
The woman thought of a body of water when she heard "Spring"

Alexander Olafsson September 4, 2013 - 7:42 PM

Nathan March 17, 2014 - 9:23 AM
