Yes, I'm a straight white male but in this context is doesn't matter a whole tonne - the reason why I say the rape culture thing is nonsense is because western culture is far from a rape culture, if you want to see that sort of thing I suggest some of the smaller Arabic countries could help enlighten you. Is there inequality? Yes. Are there people working towards ending it? Yes. Problems don't resolve over night, but they certainly don't resolve when they're turned into us vs them situations.
Agreed, I do think we as a nation tend to over dramatize and overuse some words, one of them being poverty. We don't really have any idea of poverty compared to some places in the world. We have some tragic cases of some extreme poorness.
As for the question of if we have the right to decide who's silly for being offended, you should surely know that just like the offended, we're expressing our opinions too. There's no special agency that will enforce my opinion upon others because I sit higher in the privledge ladder. If there was I would probably be a much nastier person for it, so I'm glad there isn't.
Nicely put.
Edit: RE Your post above, it is definitely rape, she didn't have a swathe of options, but she did know who Ramsey (AKA The Bastard of Bolton) was and what he was. His reputation has been well known in the North, and then there's the fact he's son of Roose Bolton, head of a house who's banner is the flayed man. The bloke who killed her Mother and Brother in the most dishonourable way. The Bolton's aren't a surprise to her.
I do see both sides here, but internally, it doesn't sit right with me to call it rape. She knew (categorically) that sex was coming after the wedding. Was it pleasant, gentle, loving? No. Definitely not (Also it's worth noting that sex for the first time is painful for lots of women, often for many times subsequent too. Could she reasonably expect such a thing (Love making as opposed to sex/rutting) when she was clearly not marrying for love, to the family who butchered her family (To a guy called the BASTARD OF BOLTON no less), I don't believe so. I don't know what I'd call it, but rape is a bridge too far (in this context, taking into account the time and nature of the people involved, and no other for clarity).
As to the question of whether it was required to be there, you should pretty much apply that acid test to almost all scenes. The series is Gratuitous, I've seen it in every episode. I differ in the opinion that I don't think the scene was included to show the rape for the sake of it, I possibly believe it's more part of the plot line of Theon and will be relevant later in the series perhaps. IE it's not part of the Sansa storyline, it's part of the Theon/Ramsey story line. I find people who are offended by this more than many of the other sickening scenes have pretty selective moral outrage. There are a lot of scenes which could be deemed as "unnecessary" in this series, if "gratuitous" is your benchmark.
