I came across this question on Quora and it has, as usual, some very good and interesting answers, and some silly ones. I want to draw attention to Allen Lobo's terrific answer, based on objective fact, and, in contrast, Laura "Bisexual cisgender female"Hancock's answer, grown out of and feeding into the deluded, counterfactual feminist mythology. Also Layla May's answer, which shows commonsense and down-to-earthness very thin on the ground these days.
