People need to realize people reflex post random shit on social media all the time.
How is this really any sort of defense though? It didn't really fly when Dana tried it at the press conference, either.
Also, if there's going to be a movie made about her,
guaranteed it's not just gonna be some forum jockeys bringing this up. It's
going to become a big deal again, and it'll have to get addressed for the first time since 2013 otherwise it'll just be a cloud that hovers over all the pre-release publicity and marketing.
It's not like she can't completely shitcan all of it by straight up apologizing for being stupid and speaking without knowing what she was talking about. It wouldn't be hard for the mea culpa to read like "I don't believe that stuff, and I'm sorry I ever shared it." It would take all of a single paragraph in a single press release to squash it entirely, as opposed to having it linger like it's done for two straight years now.
But even if she does all that, as has been pointed out earlier in the thread - she's fucking terrible at acting, so this is going to be a problem production regardless.
edit: 8 Mile was fictional. Not to say there weren't similarities - but it's not the same thing.
