If you make a statement like which sex is more emotional, you have to be able to prove it. To prove it you need to be able to measure it. To measure it, you need a meaningful metric.
People say that women are more emotional because they throw hissy fits, and cry...etc when they are upset. All things considered, that it pretty harmless to themselves and others. Just like when men shout in anger.
But if you consider the impact of emotions, ie real impact, take a look at what each sex is willing to die for, and more importantly to kill for.
That metric will show you that women, like most men, will die & kill for their children, their homes. So will a bear or a cow. Big fucking deal. A woman's emotions are indistinguishable from a wild animal's, and can therefore be tamed by the circus master.
Men will get their balls shot off for stupid notions like their country, flag, political affiliation, race, traffic rage, bar fights, pride, social status, an insult, a chick...etc.
More importantly, many men will also kill for the above reasons, but also because they think God is on their side, someone stepped on their property, they were ordered to, they think they can drive aroused by Margaret Thatcher and Ronald Reagan, power...etc.
Women manage their emotions better, and while some of the above occurs in that sex, it is mostly because of vestigial testicles.
