TATTOOS... Oops, did I say that loud?
So, in a pony society with modern technology like smartphones, probably full of accessories, and no magic. Well, history (old pictures, cave paintings) they do have, so of course they know every single pony since forever ago had a cutie mark. I am worried this is oversight, but G5 has opened the doors for ponies to have tattoos. There is no magic to erase/limit such a thing.
I remember from the early Brony days about people being upset of the episode "Call of the Cutie", for telling young girls to get tattoos.
Here is some of my own questions and answers to try to make sense of things:
-They won't have tattoos because Equestria's magic prevents it?
Magic is no more.
-Having a mark/symbol on your body is considered against the law/not allowed?
MLP is defined as a plastic pony with a symbol on it. If G5 is the first to remove that, I would be surprised. It is like removing Coca from the Coca-Cola brand.
-Tattoos haven't been invented in Equestria?
But Smartphones have?
-They aren't called tattoos to not upset anyone?
That is a possibility. But then, let's change the word smartphone as well.
