The times when they talk about Faunus you just don't get the impression that Ruby or Yang know too much about them. I can imagine Yang playing dumb, but Ruby is not the playing dumb type. She's the being dumb type. I will give you that we don't know if Qrow would be a full-blooded faunus or half.

However, we don't really know if Ruby knows Yang and her are only half sisters and if she knows, that Yang's biological mum is (potentially) Qrow's sister. Ruby hasn't gotten to say anything about her parents.

And, again, "the times they talk about faunus" would be when they see Velvet being bullied, when Yang was the only one who made a faunus specific related problem, everybody else talks about Juane's problems; and during "The Stray" and "Black and White" again, Ruby doesn't really say anything, she just listens to Blake and Weiss argue and tries to pacify the situation, the one who tries to express her opinion on it is Yang and she is ignored, that doesn't mean Ruby doesn't have an opinion herself.
