The video announces that the green party have awful policies such as:
- Oppposing discriminatory hiring policies in schools!
- Favouring more effective counselling services in schools which will cater to people from multiple faiths and cultures!
- Promoting effective abortion provision for women who wish to terminate their pregnancy!
- Encouraging setting up effective euthanasia provision for people who wish to end their lives prematurely!
(In the case of the last two, the video even says "provide effectively".)
- Arranging state recognition of gay marriage!
- Opposing unfair discrimination in the adoption system, ensuring that children are not unfairly prevented from entering a loving family!
ZOMG THE MONSTERS!!!!

Researching further I found this comment. I'm not sure if they were being serious:
If we get an Atheist PM, does that mean we will lose holidays like Easter and Christmas?
