I see women as dangerous as men, and also more prone to violence than many give women credit for, just as men can be just as manipulative, gossipy, and passive aggressive (more so than plenty of women). I think women are as obsessed with sex as men and men as obsessed with romance as women, but that neither are as obsessed as they're portrayed to be, generally speaking, though both feel they have appearances to live up to, and social factors tend to inhibit or exacerbate certain traits, but remove that factor and the effect can instantly disappear (and sometimes even when present can't stop or inflame it).
Just to be clear, I do think this is an unpopular opinion (and taking this thread title at face value). And again, the above is generally speaking with plenty of exceptions (some way too obsessed, and some who couldn't care less one way or the other and aren't afraid to show it, not all are violent and not all are passive aggressive gossips, etc). And though I'm cynical I'm not paranoid. Perhaps it's why I tend to give the characters (like Xander and Cordelia) in Buffy a bit more of a break than many do.
