I can't stand him.
He's obsessed with identity politics and "trans rights". He says that repeatedly misgendering someone (ie using factual, sex based pronouns) is harassment and shouldn't be tolerated.
He has said that there is no place for gender critical people in the Green Party. Very much listen to the science when it comes to climate change but ignore the science when it comes to biology.
He opposed the Cass Report which is all about safeguarding children and the Supreme Court judgement which clarified the Equality Act and made it clear that women have the right to single sex spaces.
Zack has a huge ego and makes everything about himself.
Newspapers called him a surprise candidate for the leadership campaign but he had been planning it for a long time.
There's a newish left wing group within the Green Party called Greens Organise. They managed to get lots of new members to join the party and all voted for Zack. Most are young and for many, trans rights are their top priority with Palestine 2nd (situation in Gaza is clearly terrible and should be a priority but this comes way ahead of anything else for Zack's new followers). Little interest in Green issues or other groups who need support like women, disabled people or the elderly.
Many very long standing members who are committed to fighting climate change and the nature emergency feel increasingly marginalised within a party to which they have devoted decades of their lives.
As an ex actor (go on IMDB and you can find a clip of an awful film he was in. I forget the exact title but it's about a challenge to drink a load of milk) so can make speeches that get the viewer's attention.
But he's used to talking to crowds of supporters and forgets that people outside his bubble have different ideas and that those people aren't necessarily idiots or racists.
He's not as an astute politician as he thinks he is. He doesn't stop to think how his words will be perceived by people who are outside his bubble.
Already we have had an article in the Daily Mail, reporting on a radio interview and saying that Zack thinks it's ok to shoplift if you're hungry.
A couple of days ago, The Telegraph reported an interview that Zack had given to another paper in which he appeared to say that only poor people are racist because you have no need to be racist if you are comfortably off. In that interview he managed to both insult poor people and ignore the fact that there are racists in all sections of society (the aristocratic Oswald Moseley and middle class Nigel Farage being 2 prominent examples).
He's been elected for a year and I hope he doesn't do too much damage to the Party in that time.
