Fvck me.
Don't get me wrong, she's a nob and she was objectively in the wrong but this is a bit of a melodramatic over reaction. It's a silly reality TV show ffs.
To be honest, I highly doubt she was offended, it's just an act isn't it? She's a professional YouTuber. It was all so very forced and over the top it struck me immediately that she was just trying to be deliberately controversial for the attention. It's worked, she's gone very viral.
If she thought it would go down well with the public it's probably a misstep because she's somehow made herself less popular than Nigel Farage, she'll probably be the first out. But she might have anticipated that anyway and just gone for some notoriety. It's quite obviously a gimmick.
