That doesn't say that there aren't downsides though. It said both genders are evenly represented in 'most' organizations, and that they're generally equally treated. I personally never interpreted as to not having sexism in Thedas. That very texts made me think that there'll be sexism sometimes, and that women might not be rapresented in every organizations at The same level of men (The opposite in this point is true as well. Women are The only ones who could lead The white Chantry, or that can be a Rivaini seer).
While I think it should've been clearer, I personally don't see how that text states there isn't sexism in Thedas.
I'm not going to quibble about how your interpretation was different from my own when I first played... since getting to choose a woman is a pretty special thing with these games for some women. Sure, in hindsight one can textually analyze the qualifiers in there. In terms of pure gameplay, the point of telling you this in chargen, the first thing you learn about Thedas, is that choose a woman or a man, doesn't matter cuz it's our new fantasy world. In practice, it's our same world, just different proper nouns. For me the emphasis was on 'equals' not on 'generally,' hence my disappointment.
Regardless, now we know, and given everything we've seen since... it makes more sense. So, yay?
