Seriously. Female is the opposite sex to the male in all cases. Animals have females too. Some people like 'em, some don't. The end.
Females are not aliens.
Females are not genetically deformed.
Females are capable of compassion, as are males.
Females are capable of nastiness, as are males.
Females don't need what most feminists call 'equal' rights.
Females are different to males, therefore should get rights which suit them, as should males.
Males don't get pregnant so they can't take a holiday for that, now can they?
Above referring to human females, however, some or all of these statements may also apply to other living creatures of the Earth.
