The reason she said this is because he’s having to wear a dress and high heels while also hiding his identity, which is likely to be a significant disadvantage.
 
Has nothing to do with sexism or any of that nonsense that I’ve seen some people claiming.
 
@Vaidelot  
No, it isn’t. The show has never portrayed one gender as advantaged or dominant. Equestria is gender-egalitarian.

@albert19
 
Huh, well then I’m just confused about her suddenly being fired at the season premiere.

@Nordguy  
We are all on board that Orchad Blossom is an amazing, beautiful mare who had the exquisite bravery of a breezie flying against the wind.

@Dirty Bit  
You’re wrong in for all three, since the voice actress for Principal Victoria also does Stan’s mom, the mayor, Wendy, Shelly, Cartman’s mom, and Kenny’s mom.

@NiGHTS4life
 
Same here. Usually, characters being knocked off on certain shows means that either:
 
A.) The voice actress of Principal Victoria has died
 
B.) There was a dispute about her contract and she quit the show
 
C.) She wished to work on other things, voice acting or otherwise.

I already miss Principle Victoria from South Park.

@Vaidelot  
we must worn the princesses!!!

I really hope they have a good setup for PC Principal and PC people in general.

Orchard Blossom is a brave and stunning mare.

@Background Pony Number 17  
She wouldn’t admit that anypony, mare or stallion, is better than her.

@Marusame  
I think it’s more a case of Rainbow Dash being Rainbow Dash. You think she’d be the one to admit stallions are better at sports than mares?

@Background Pony #853B  
South Park will gladly take the piss out of anyone.

@Background Pony #853B  
They were poking fun at SJWs. Hilariously enough, SJWs got pissed and became the parody themselves through their obnoxious behaviors. Satire became the accurate truth!

@Background Pony #853B  
No, they’re parodying political correctness.

@SeraphimDawn
 
So South PArk is now Poltical Correct show ?

@Marusame  
Well, many of the challenges seemed to favor smaller, more nimble ponies, Big Mac sort of was at a disadvantage as a stallion.

@semerl  
“Politically Correct Principal”

@semerl  
No, that’s a character from the “South Park” show. He’s a grade school principal who always beats up anyone that’s not PC.

Personal Computer principal? (Don’t get me started on Principal Celestia)

I need to dye my hair red and blame everything wrong on the EVIL MATRIARCHY!

Matriarchy in Equestria confirmed!

wait… re reading that line its presuming that the females are indeed considered to be more physically capable? Interesting concept that stallions have a harder time than the female horses.

PC Principal is funny when he trembles.

@Stotter  
And so it has.

It begins.
