@Align  
Right, because Spike’s a girl.
 
Keep in mind, this is also the kind of show where you could reasonably expect the genders to be color coded.

if you’ve never seen (or heard of) tomboys…  
though to be fair the meta-knowledge of “this is aimed at little girls so all the main characters are going to be girls with 100% certainty” would’ve been enough for me

It’s not like the guards had a speaking role. One could assume that Rainbow, the blue tough guy, was just a younger male.

chariot/palace guards were distinctly male though

Well if it was their first episode watching it they wouldn’t know that mares and stallions have different snout shapes.

I’m guessing its partly cause people have already drew him that way… And partly (as depicted here), for the comedy effect…

That’s how headcanon works. All the male stallions get gay shipping, some just happen get it more than others.

I honestly thought Rainbow Dash was male until the second episode.
BiggerMac

Though I have no problem with people having their own headcanon, I really would like to know why and how Big Mac strikes people as being gay.
 
To me, Big Mac doesn’t have enough dialogue or screen time for someone to truly know him inside and out.

That’s because they started dated when each thought that the other was a stallion.
