As I said, he did blatantly say that there was something wrong with anyone who doesn't believe his Rosalina theory. Most other instances are the sort of thing that gets buried in YouTube comments sections of other videos (I recall him and other theorists trying to advertise the theory, as it were, on both the Completionist's and SomecallmeJohnny's Mario Galaxy reviews, by basically trying to spin it off of things the reviewers said in their reviews - in the Completionist's case, it wasn't too bad, since they are friends with him, but in SomecallmeJohnny's video, it was completely unwarranted) and such after a while though. Convention related stuff is word of mouth, but his fans wouldn't say they have problems with his attitude on his theories if there wasn't one to begin with.
Also I believe he communicates thoughts like this on Twitter.
Ah, okay. I wasn't aware.
No, the Rosalina theory is 100% wrong:
No, because Rosalina is ambidextrous, and he would not accept that. His genetics research failed him.
That's why I said "I will admit, however, that the handedness bit was pretty mislead" in my post.
It's not an interesting coincidence, because there is no connection to be made. For starters, genetics research really has no place when talking about cartoon characters to begin with, because any animator will tell you that different rules apply. Game characters are not born by genetics, they are imagined by a designer, and real genetics can only apply to a game with a realistic art style. Therefore, when trying to portray a connection to between two characters in a cartoony game such as Mario, you approach it in different ways. For example, by giving them similar clothes, like Mario and Luigi do - because they are brothers, you need to portray a sense of similarity between them, so you give them matching outfits, as well as a moustache. Similarly, characters are designed to reflect their personality traits. For example, Rosalina is so tall because it is not only associated with ethereal beauty and elegance, it's portrays a sense of power and authourity.
I'm aware that cartoon characters aren't actually the result of genetics. I'm saying it's interesting (to me; it's fine if it's not to you) that these characters share certain traits.
MatPat did at one point say that Rosalina and Peach having similar ears was a connection too, but it isn't - every human bar Wario and Waluigi in the Mario universe has round ears. Even Daisy does. If you're gonna try to use ears as a "genetic link" between Rosalina, Peach, and Luigi, you'd have to try and force a bunch of other characters in there too. Plus, there is no reason why Rosalina can't have a certain eye colour, or a certain ear shape, and even if it did "fit" (which Rosalina does not with Peach and the Mario Bros in this case) in the connection, it doesn't have to mean a relation. Because you'd have to do a lot more than that - people share similar qualities all of the time, while being completely unaffiliated (I can't even count the amount of times I have been told I look like such and such a celebrity and what not). There is no "interesting" coincidence there. Rosalina and Peach share a few VERY vague similarities in appearance, and all are by virtue of being drawn in the same art style. Other than that, they don't even look anything alike.
I never said that the genetics (or as much of it as a cartoon can have, anyway) proved anything. I said it was interesting to me personally. There is an "interesting" coincidence here... to some people. It's an opinion. The episode interested me, but it apparently didn't interest you (which I'm fine with; if you don't like it, that's nothing for me to get negative about). That's your opinion.
Hyrule Castle looks a lot like Peach's Castle, as do a lot of the other castles designed by Nintendo in their games. It doesn't mean anything. Nintendo just base all of their castles in fantasy games off of the Victorian architectural style.
Again, I never said it proved or meant anything as to Rosalina's origin (I actually said that the castle in the storybook is likely the one Rosalina and the Luma built in said storybook, if you had actually paid attention to the whole post, which you apparently didn't). I just said I thought it was an interesting coincidence.
There is a degree of objectivity to what is and isn't interesting actually, and I have just demonstrated it - sometimes you only find something to be an "interesting coincidence", because you are ignorant to the facts in play.
"Interesting: arousing curiosity or interest; holding or catching the attention." -Google Search
It aroused my curiosity and my interest, and it caught my attention. It apparently didn't do that for you. It's an opinion. That said, there is a degree of objectivity (X person found Y thing interesting), but whether or not something is interesting to someone is subjective, but you can't just say that something's not interesting (an opinion) and present it as a fact (which was one of your main criticisms on the show, was it not?).
