The problem with English is that his views are very backwards and harmful, he voted against marriage equality, he has said that he want's to keep abortion as criminal law rather than making it a health issue, and he has been a climate change denier. He's moderated a little bit as he wants to appear more reasonable to get the vote and so the only "good" part about him is how spineless he is.
We have a lot of important issues that the next government is going to have to address, issues like automation and a roadmap towards UBI, the removal of prohibition on marijuana, the legalisation of euthanasia, further movement away from the notion of binary gender, etc. and we don't want someone who's going to make decisions and lead our government based on religious beliefs rather than fact.
Unfortunately National will win the election again, the left is too fragmented and a number of people will vote National just to stop the Greens getting into power without actually looking at Green policy.
