That article is important this is a major issue for one of our main parties. As the recent disaster faced by the Lib Dems over Natalie Bird proved these ideas are illegal. Women and men do exist. Saying they do isn't wrong.
So the Greens are going to have to face that reality soon as the Legal cases for Emma Bateman, and Dawn Furness are still incoming [gardening needed]:

Sounds like Ali might have to go to court again.
As for a SEEN group. The reality based Greens are already organised within the Green Party Women and the Green Party Women's declaration, a bunch of people have been expelled or suspended, but others remain. Thousands of members voted for Shahrar as leader.
This is all going to have a political impact on the Greens soon or later if they keep losing cases and money. The next council elections are in May and they are going to need funds.
Also this issue is politically useful. The Tories will be defending a lot of seats so if they go after the greens for being sexist it could be a wedge. Labour also have choices to make. Unlike the Greens they accept the Cass Report so they have leverage there. Do they not use it or not.
Going to be interesting to see what happens at the Greens conference too.
