I favor pony Twilight.
Life is simple: it has no nontrivial normal subgroups.
It doesn't matter, they are animales, unlike with the whitewashing of Korra in fanart, they have no set skin tone.
I'm with story. They're ponies, so they don't map to human ethnicities in my mind.
Yeah, there are always those few people who are idiots about stuff like that. I mean, I admit that I'm not a huge fan of stuff like Black Twilight (mainly because all the voices actresses sound Caucasian, so I have a hard time imagining the ponies as anything else), but I've got no gripes with people who interpret the characters that way.
Yeah, it really comes down to personal interpretation.
Fucking auto correct, that's suppose to be Twi.
