I'm questioning whether she was offended at all. She certainly has the right, but her actions before and since (ie at previous speaking events, comments on her twitter feed, mishearing an innocent comment as a sexual one) beg the question.

And yes, sadly this is relevant, because, as much as we all have the right to decide when we are offended and not, there will always be people, consciously or not, who will game the system.

And you aren't offended by people who walk slowly in front of you - you are annoyed.
