I do agree, Big Brother had an interpretation problem and whether you like her or not, it's unfair. She justified herself but BB already made a decision.
The way BB said it appeared as kind of 'offensive' but in the original context and considering how Alex lives, it should haven't been seen this way.

As for Emily, it is completely different, she justified herself by saying 'But we all say that' or something in this way. She may hasn't been racist but she should have never said that clearly.
