You're attacking my points here. Playing the victim because you still have utterly nothing to prove your case while I have plenty here but yet you're still insisting I have nothing. It's the equivalent of you saying you're winning despite launching no effective offense against your foe.
You're forgetting one thing but let me say it again the op never said comics weren't allowed. Whether you like it or not, the comics are b canon so thus I can use them as I please here. Until you're the op himself, you can't change the rules here as you like because of your cherry picking antics.
They're all mentioned and done in the comics. Okay I'm getting tired of your incessant attempts at disproving this point of how the show doesn't mention despite how:
A. The comics themselves don't mention every episode that happens in the show. Why aren't you complaining about that too.
B. They operate separately in the timeline so as to not bother them with each other and to keep things in cohesion together to ensure the canon is at least stable. Also it helps to ensure writers aren't too overburden with learning both sources in writing an issue or episode for their respective media.
C. The comics are 'b canon'. That means it exists so long as the show makes no contradictions to the issue. The show does not need to make mention of the material nor vice versa in order for it to be canon.
D. A major comic book artist said that 'Hasbro' the company that monitors and determines everything both the show and comics have considers it canon. This is what drives me up the wall with your denial as you're denying word of a creator from a major employee that the comics are canon. As I have said before, Hasbros word >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> a fan's wanton wish. There is definite proof the comics are canon by Hasbro. Their view is the only thing that matters whether you like it or not. You can try and deny it all you want but I'd take the word of a major comic book artist who has worked with Hasbro over a fan.
E. Equestria Girls exists too and we even have a character in Flash Sentry being shown in a S4 episode yet the show has done nothing to make any direct mention to them. Why aren't you attacking Equestria Girls in the same manner or is it because it would actually validate the point that the comics operate in their own separate timeline much like how Eqg does the same too.
F. A little tidbit to add. Remember how Babs Seed got her scissor cutie mark that was mentioned in the show? That was first established in the comics. So here's a direct reference the show made from the comics if the pony ocs of the major comic book artists aren't enough for you.
The only thing that is question in canon with the Journal of the Two Sisters is whether the Alicorn sisters were born alicorns. The rest is fine. This was explained over in EQD where Amy had to be dragged in to explain it: http://www.equestriadaily.com/2016/03/amy-keating-rogers-explains-her-ideas.html
As for Josh Haber, he was being coy and is letting fans decide for his own amusement about the whole thing and considering how it's worded. It could be argued it didn't removed it from canon as it can be explained they have no idea how to create an alicorn baby naturally. After all they were just babies so the fact the sisters have no idea can be explained that getting an Alicorn baby conceived takes some special circumstances to get it done.
Also in the S4 episode Castle-mania, it was shown that Twilight was busily reading a book called 'the Journal of the Two Sisters'. Thus it's still very much canon as the show itself mentioned it's existence.
Yet Luna didn't so thus whose fault is it that decided to be lazy with studying magic while her sister was busting her flank off trying to learn as much magic as she could?
You're just throwing antagonizing statements at my case and yet you have none of your own to really prove. Here's the thing, in a debate, it doesn't matter how many points you can prove or disprove on my end, if you have no case of your own to prove your points, all of your attacks and conjectures means nothing. Until you can actually have a case at how Luna is more powerful than Celestia that does not depend on some faulty and not similar analogy, I don't see any reason to agree with anything you have written against me.
