Reading people's comments on social media on the issue, people are defintely on her side. So I don't really think she has become a joke, at least not for most people.
Kangana has not proven anything because she was not the one who had the problem. Hrithik started with the imposter thingy, so the onus was on him to prove, if anything.Someone who can prepare write so many emails to build proof two years from before and then accusing the other person of sending those mails is definitely not the work of a very clean and clear mind. So yes, if Hrithik did that he was indeed capable of doing more. She is addressing her own fears that she underwent at that time.
