Your statement wasn't about rejection as you used Jodi Arias as an example. That wasn't the motive for her crime, so I assumed that you were opening the discussion up to murders between intimate partners of which men commit many more than women. You guys cry about women never approaching all the time, but you want us to believe that in the tiny amount of times they do they're murdering men who reject them on the scale that men murder women who reject them. I will concede that it is a tiny percentage of men who resort to murder women after rejection.
the whole discussion you opened up was about men being more likely to react violently to rejection. jodi arias murdered her boyfriend because he wanted to end the relationship, which is a form of rejection.
edit: there are different forms of rejection. you can get rejected when you approach someone, you can get rejected when someone tells you after one or more dates that it's not going to work out, you can get rejected when someone ends a relationship.
woman might not openly approach someone, but they give signs that they want to be approached. and yes, most men will tell you that in their experience, woman handle rejection worse, because they are not used to it. they think men are supposed to chase after every p*ssy that is offered and if they don't, something is wrong. wether cociously or not, a lot of woman base their identity and selfworth on their desireability. in that logic, getting rejected means they are not desireable, which is why rejection hits them harder than men, it fukks with their ego, self-preception and self-esteem. some will chase you harder after you reject them or immediately offer themselves to another man to prove to you and themselves that they are still desireable. but a lot will rationalize that something must be wrong with you (gay, insecure etc.) and insult you, which is what the girl in the op did, and what is already a form of violence.
