Mm. It could, I know a number of shows have seen their viewership go up from that direction when word gets out that a happy LGB romance has been introduced. But there's also the parent demographic to consider, and a lot of more conservative parents might unfortunately change their minds about this being Good Clean Fun for their kids if they felt like the show was trying too hard to be Political (which I think would be pretty stupid but it WOULD happen), and there are some conservative types mixed in with the brony viewership as well.
Also, if they were trying to appeal to LGBT folks, they already made a point of denying the Lyra/Bonbon are a ship headcanon (unless you're looking really hard for subtext), and I know of at least one member of the T demographic who'd previously been a fan who was deeply disappointed in the episode where most of the plot is Big Mac in drag being played for laughs... So I don't know if it's particularly likely for the showrunners to make that call at this point.
Well Big Mac only was in drag so that he can compete in the Sisterhoof Social with Apple Bloom since Apple Jack was at Mane Hatten during that time. That proves he'll do just about anything for his family. As for Lyra and Bonbon, there was that dream episode where they were attached to each other and they were happy about it.
What about Fluttershy and Rainbow Dash? I've seen more fan art about them.
The Big Mac thing... it's - it's a Watsonian vs Doylist problem. Like. Every story, there's a way you can look at it as "why would the characters do this," but there's also a way to look at "why would the writers do this." And from the character's view, Big Mac was trying really hard to do something sweet for his sister. But from the writers' point of view, watching Big Mac put on this very over-the-top personality and the amusement of the ponies around him - to someone who doesn't conform to their assigned-at-birth gender watching, "a dude dresses up as a woman and totally can't pull it off, he's hilarious, that's the joke," can seem very awkward.
I don't have strong opinions about FlutterDash but there's obviously plenty of history between them, and they could be very cute together if the writers ever cared to do that. ^_^
Mm, I think flight training can actually be serious business. But Soarin' does seem a mite flighty for her at times. I agree he'd have to prove himself a bit more if she was the Apple for him. It's a big family though - he could be seen hanging in the background with one of the cousins some Two Hearts Day and I'd be satisfied. ;)
Hm... As things stand in the show his crush on her is kinda cute, but not going anywhere. She is, as far as we can tell, a grown mare - living on her own, has a business and a position of national responsibility - and he's something between one of her best friends' very young little brother and adopted son. That doesn't really work for a two-sided romance.
Outside of the show, though, I could definitely see it as a possibility - depending on how Dragons age relative to Ponies, and I'm assuming at this point that the dragons in various stages of growth who were still articulate in the Dragon migration eps means the crazed greed-growth thing is something like a freak magic outlier rather than a consistent representation of How Growing Dragons Work - he MIGHT be able to reach maturity during her lifespan, or in fanfic maybe we could hypothesize the Elements prolonging their bearers' lives to keep them around while they're needed, or a Rarity!Alicorn AU or something - there are ways they could both be grown enough for it not to be weird for her to fall for him in return. I don't think interspecies romance is totally off the table in a world where so many different creatures are all still People, although short of magical intervention a species gap that large would probably complicate them ever having kids - and there's a certain amount of poetic logic to the idea of a magical jewel-finder and a Dragon.
Well, canon doesn't give us a whole lot of romance that's spelled out in capital letters, and shippers tend to take what they can get. :p And I do think that in the future, depending on how he grows up, it's not out of the question. But I like to see other options explored for them in fanworks - Dragon OCs for Spike, Canterlot nobles or fellow-artists or other members of the Mane 6 for Rarity.
...Don't think I'd go phoenix for Spike - they're less People-like than the other options. They MIGHT be People, but I haven't seen strong evidence of it? Like as far as we can tell, Philomena, or Peewee's parents, have been more in the dog-to-dolphin/octopus range - Very Smart animals with a lot of personality and some strategic thinking, but not sure about their level of self-awareness and interpersonal communication. Opinions? Do you think phoenixes are People in the series in the same way that a Pony/Dragon/Griffin/Buffalo/Yak is a Person?
Actually, I find it a little weird on review that Fluttershy was so surprised Spike could talk - she's an animal specialist, is Dragons being People not actually that common knowledge? Is that just because Dragon colonies tend to be so isolated, or are most Dragons you encounter in Pony territory the greed-grown sort, or what's going on?
Hm... That's a point. Maybe she heard some Scary Dragon Stories as a little filly and never bothered to research them further because of the intimidation factor. And the sort of foals who might tell scary stories about dragons probably wouldn't bother to include the "and they are people" part, yeah?
She might be scared when she realizes initially. But... I can't help thinking that if she watches him grow up slowly, it won't be the same kind of fear as for a Suddenly Adult dragon? Like - she knows who he is. She will've been there for every birthday along the way. Listened as his voice changes. Even if she feels a shiver sometimes looking at a Wall of Purple Scales, I don't know if she can go from seeing Spike to seeing him as Not-Spike-Actually-Scary-Dragon. But I guess part of that depends on the nature of the fear. If it's like a full-on phobia... I don't know how they'll deal.
