It would be like, say, promoting Black Widow in AoU by ONLY releasing the clips where she talks about wanting a relationship, etc. Clearly not the only aspect of her character, but you might not know that if that clip is all you saw.
The thing is, the clip doesn't demonstrate Claire as a "bitch." She's pretty cold toward the dinosaurs and sees them as "assets" because that's her job, but other scenes have been shown that puts her in a powerful context, like her holding the flare clearly trying to get something's attention. While she may seem stiff in that clip, she's discussing business with Owen, but where they had a failed relationship he couldn't help taking a couple of digs at her, which she obviously found playful. Had she looked pissed off or something that might be one thing, but where she smirks and rolls her eyes, it's evident that she can take his jokes and has before.
When you know someone and know how they tick, there's some loosening up and you can pretty much say anything and the other person will know you're kidding. My friends for example are very much guilty of this and we usually greet each other like "sup bitch" or something but we're not being assholes. That's what was happening very clearly in that clip, just two people that know each other and can take potshots. Had Owen never met Claire prior to the clip and it was just him trying to hit on her in a sexist way that would be one thing, but they have a prior relationship. This example is what I mean when I say that some people try way too hard to look for sexism in everything.
It wasn't a good choice to release the clip as they should be releasing clips that better represent the film, but it's not sexist and by the end of the film Claire will be seen as a hero.
Not a criticism. I legitimately don't know if its a a good sign or not, because the heavy amount of released material can be interpreted either way. Why the personal attack?
Not a personal attack, but in hindsight I can see why you would take my wording as such so I'll apologize for the confusion. I think all that's going on is your typical case of shitty marketing to be honest.
