Eh… I’ll come out as a Brony here, albeit not of the clopping variety, which allows me to speak more freely.

There are many SFW and even child friendly spaces in Bronydom. Many of us have children ourselves and just enjoy the neurotics and fresh silliness of the show and even sillier subculture. The fandom is just chock full of nerdy references which often got picked up by the show, because the creators are huge nerds as well and love to signal to the knowledgeable audience. Just like Sponge Bob has lots of adult jokes hidden in child friendly dialogue.
