Well, if it's not BS, then what has "Asia" done that is equivalent to the Dales?
There's got to be a better example than this.
You are missing the point entirely.
I said Sera distrusts/dislikes elves/mages based on qualities that they cannot change. Elves cannot become humans. Mages cannot become non-mages (unless you make them tranquil). That is the same thing as disliking someone for being gay, or Asian. You cannot make someone "not gay" or "not Asian."
Therefore, if you play as an elf, who appreciates their heritage and Sera spits on it all, that is just as disrespectful as someone who tells you you're stupid for expressing interest/appreciating your Asian heritage. Also an elven inquisitor is not trying force their "elfyness" onto Sera. An elven inquisitor is just like, "Here are my views. I like being Dalish. I appreciate my culture." That is how I role-played anyway. Sera, as immature as she is, gets angry because she thinks your beliefs are stupid, and essentially disapproves of you simply being you. This differs from most other companions who disagree with your actions, rather than who you are on a fundamental level.
I'd also like to avoid being told that I'm a hater when it comes to Sera. Sera, like the rest of these characters are pretend people, and I've never seen the point of hating TV characters, and the like. However, it does seem quite clear to me that Sera is as much of a racist as she is immature. It is imply part of her character. I don't know why people are so passionate about trying to disprove this fact. I don't see anyone trying to deny that Blackwall is a liar. These are just character facts.
