Qunari didn't hold a sword to the throats of the elves of Kirkwall, and they flocked to them in droves.
But no, I'm not saying Celene should follow the qunari model.
Ideally, Celene should be waging a war to win the hearts and minds of Orlais towards the elves favor. She should be hiring minstrils to sing elven songs, she should be hiring artists to paint elves in heroic stature, she should be hiring scholars to publish works on elven equality, and she should be hiring playwrights to cast elves as heroes. She should be fanning the flames of elven sympathy for years before she started making bigger decisions.
You know, when Hollywood tries that people just change the channel. I'm struggling to think of any major social reform movement that succeeded via propoganda, and I can't think of any. It puts the cart before the horse- elves need to be sympathetic before people will find them sympathetic in art and media. To take a real world equivalent, the depiction of gays and lesbians in media has increased in the last several years... as a reaction to the increased acceptance and support for homosexuals. Not as the cause.
I don't have any objective statistic, but from personal experience I've seen plenty of people simply dismiss and disregard cultural propoganda that they don't agree with. Whether dismissing it as rightwing conservative christian Fox News, Evil Liberals, Western Crusader Degredation, backwards superstition... unlike the common conceit of conspiracy theorists, people don't base their cultural viewpoints around propoganda campaigns..
But at the end of the day when it comes to a desire for equality, one should always be ready and willing to fight for it, because once you get it, the day will come when you're forced to fight to defend it.
Sure. Of course, the next morning after you may find that in fighting for equality you left behind a razed home and lost it to bloody animosity.
You can beat people up to make them leave you alone, but you can't beat them up to make them accept you amongst them. Fighting for independence has a military solution, but fighting for acceptance does not.
