Today I learned (again) that accepting people for who they are is a liberal agenda, people wanting to be respected despite their sexual orientation is a political issue, and being unashamed of who you are makes you a stereotype.
Until that's not the case, art will continue to reflect this, 'shoving it down your throats' until you realize there is nothing liberal or political about common human decency and respect.
Only once everyone respects each other for who they are, once there's no more drama and tragedy in it, will it become a story not worth telling anymore.
Amen. As I said on the other thread, anyone who screams "agenda" on these issues has the biggest one of them all: to preserve the status quo of who is and who isn't worth considering human enough to have their existence acknowledged, their pain heard and their stories told.
Let's turn it around. Clearly Dorian's father's role in this mission is about nothing but his heterosexuality. Why is he shoving his straightness down our throats? If he absolutely must be straight, can't he at least keep it to himself instead of making such a big issue of something no decent person even wants to know? What a one-dimensional failure of a character, Bioware, why didn't you give him a real, valid reason for existing, one that isn't all about his desire to have sex with women?
