Not sure why you're going into full on dick mode over a post, but hey, to each their own. As for Tyrion.. past the line, all of the reasons you've stated have been explained by the fact that is said over and over again in the show that Tywin hated Tyrion because he A) caused the death of his mother, and most importantly B) hated him because he was a dwarf and not a perfect son. In this past episode Tyrion even says this during his talk with Jamie. Past that, please show me anything else that makes Tyrion being a Targaryen so obvious that everyone else misses it. Everyone I've asked about it have all said they don't know of anything that connects Tyrion to the Targaryen. Maybe it's a book thing as you've thrown crap in here that's in the books, but as for the show, please tell me what episodes have all these obvious signs that Tyrion really isn't Tywin's kid, let alone a Targaryen. Hell, every single wiki on the show that I've seen on it (and I've been looking) ALL say he's Tywin's kid and I haven't seen any that talk about him possibly being a Targaryen.
Oddly enough then you double down on me by claiming my post that it's possible that Jon is a Baratheon yet that has more to the idea than anything you've put forth on Tyrion being a Targaryen. It's a bit bizarre that you put forth a idea that as of yet has no substance past your own wants, yet attack an idea that has enough clouding around it to make it possible.
Yes, the odds are really strong that Jon is a Targaryen, however it's also possible it's a misdirection as all the clues hit you over the head with it. This show does try to be clever and makes you think it's one thing only to flip it around.
Either way, please feel free to continue to be a dick towards me, just as long as you provide something that makes actual case about Tyrion that hasn't already been explained away in the show itself.
