In 'modern' times, this is an example of what can happen if a heterosexual male happens to ask a female to go get some coffee. After watching many videos and attempting to find out what really happened in this situation, I still don't find any evidence of anything that Ms. Watson could find so insulting at all. A simple 'no' would have most likely ended the encounter. This is more criminalization of male heterosexuality in wonderful 'modern' westernized civilization. How free straight men appear to be.
The entire reason women can make claims like this is because of the general cultural climate due to laws and social acceptance of misandry (even if it appears to be minimal problem).
