MLP was originally and obviously aimed at young girls. Although the team behind MLP:FiM has long since recognized the demographic for the show is in vastly different than the initial target audience, I wouldn't change the representation. The media is still severely lacking interest in female-centric protagonists- even rarer in the case where the females almost entirely get the noticeable development. In most cases personally, regardless of my biological sex, I have related to male characters. It's certainly not required that biological factors need to be involved for realistic characterization, or just to relate to character at all. There is definitely a prominent bias with representation in the industry. Is it safe to say MLP doesn't need a male character to take the spotlight and is perfectly fine the way it is? We certainly don't have a show akin to it.
