Women are emotionally very unstable and easy to manipulate. They are not equipped to be leaders.
I wouldn't claim that most of the women leaders are unstable and vulnerable to manipulation. But it is true that they were the ones responsible for some of the worst political decisions in the world. A few examples here:
1. Hitlery Clinton - bombing of Belgrade, embassy attack in Benghazi
2. Indira Gandhi - imposed emergency, arrested millions of opposition supporters
3. Margaret Thatcher - tried to exterminate the Irish people.
4. Chandrika Kumaratunga - escalated the ethnic tensions in Sri Lanka
5. Dilma Rousseff - wrecked the European economy
6. Angela Merkel - destroyed the EU
7. Yingluck Shinawatra - stole money from the treasury
8. Irma Grese - crimes against humanity
9. Queen Mary I - genocide of protestants
10.Ellen Johnson Sirleaf - failed to act against the Ebola epidemic
