I find that the denial of PMT, by at least one of the female contributors, is self delusory.
Being able to admit that there ARE gender differences, would go a long way towards creating a better relationship between the sexes......then we can move onto something else...racism, poofter-bashing, smoking, drinking.
To deny that, as humans, we discriminate on colour, religion, language, sex, wealth, age, size, etc. etc., is denying the truth.
