Yeah, after all of those safe stamps I had to make this.
For those who didn't know, the whole 'Rainbow Dash being a lesbian thing' first came from a woman who was criticizing the show, saying that Dash "made all lesbians look like angry tomboys". Ironic, considering she appeared like she first had intentions of protecting lesbians in mind, then immediately went to say that being a tomboy made you a lesbian. I'm guessing she also saw the rainbow colours and that brought her to saying that as well.
From there on there have been actual fan wars about it. But really...why the hell does anyone care? If people do believe she's a lesbian and they're not trolling, good for them. If people don't believe she is, good for them.
She's just a cartoon character. There have been some children's cartoon character whose sexualities have come up to question (Spongebob being asexual, Ren and Stimpy being gay), but all in all...why is there so much fuss about this? Why all the arguments about it?
Just because one dickcheese of a reviewer said she was everyone in the fandom has to go absolutely fucking insane over it? Stop acting like whiny anime fans who figured out that the main character in some anime comes to not fall head over heels for the obvious love interest.
Just enjoy the damn show. Most of the people who will say she's a lesbian do like shipping (though, even I like shipping and I know that canon there is no indication to sexuality), and if you don't like it ignore them. I repeat from my "BUT IT'S EVERYWHERE" stamp: IGNORING. IT'S FUCKING MAGICAL AND PRETTY EASY TO DO IF YOU STOP COMPLAINING FOR A SECOND. C:
In my headcanon, everypony is bisexual. It makes sense to me because the ratio of stallions to mares is like 1:7. In my headcanon, Equestria doesn't care about gender, it's about it's about whether you love that pony or not.
