Now, I'm speaking as someone who actually likes realistic RPs (which, so far as I know, has had no impact on my intelligence), but to me it seems rather narcissistic to expect an already established realistic lion RP to bend its own rules and let in an impossible hybrid that won't fit in with their theme just because you want to join it. If an elemental snow leopard wanted to join my post-apocalyptic dog RP, it wouldn't matter how good they were, or how few elemental leopard RPs were advertising at the moment, or that I actually like snow leopards a lot, I still couldn't let them in because it would throw off the entire theme of the group and everyone who actually joined because they wanted to RP city dogs would have to work around a giant elephant in the room. I know being rejected isn't pleasant (and seeing as I'm fond of robot characters, it happens to me a lot), but its doesn't fall on the people who run their own themed RPs to make exceptions and go out of their way for you.
