One, it was arse-clenchingly cold.

Two, I warmed up due to a mega blush caused by asking Jeremy Corbyn — one of only two Labour MPs who showed up, we invited them all — if he was from the Labour Party and him drily responding: “Your research precedes you.”

Three, the lukewarm but heart-wrenching lack of surprise I felt when I saw the story on a fellow protester’s placard: “Evicted For Being A Woman Who Answers Back.”

It stuck out from the other signs like a sore thumb. They told stories of landlords evicting them for reasons of pure greed — refusing to spend the money on repairing busted front doors, fallen-though ceilings, leaky roofs.

This one was that and then some. It summed up perfectly why women are hit particularly hard by the housing crisis. On top of the black mould and power-mad letting agents suffered by our brothers, we get a big fat steaming heap of sexism.

Not just the direct sexism of landlords, but the inherent sexism of society. Single mothers keeping a spare room for family members helping with childcare — or for children who don’t live with them all the time — are hit hard by the bedroom tax.

Women who need to flee domestic violence find it harder to do so when finding affordable, safe accommodation is almost impossible.

Women as a whole have been hit harder by the cuts than men, meaning that, even all else aside, many of us struggle to make the rent.

Woe betide, too, women who happen to be part of other groups society historically loves to hammer.

Women of colour who have to suffer letting agents prepared to only pass on white tenants to potential properties. Women whose nationality will mean a side order of suspicion and xenophobia with immigration checks by landlords. Women with disabilities who after every eviction have to start the search for an adapted home all over again.

LGBT women who are likely to face discrimination from prospective housemates and landlords before they’ve even moved in.

So when our fellow GMB activists, GMB London Sisters, asked our group to host a joint event with them, the subject we were going to pick was obvious. Not just because women are so badly affected by the housing crisis but because we’re also the ones at the forefront of the fight against it.

Rosie Walker, the woman who answered back, was made homeless by that eviction but formed a renters rights’ group — Waltham Forest Renters — when she found a new place.

Betsy Dillner, director of Generation Rent, is a legend in our eyes, not just for turning up at the icy-cold protest with a huge vat of mulled wine and a sausage dog, but for leading an organisation which has put renters’ rights and the housing crisis centre stage in the national press.

Eileen Short of Defend Council Housing is a stalwart campaigner, enthusiastically encouraging young activists she comes into contact with.

Groups like Focus E15 Mums have inspired thousands of activists up and down the country through direct action and a no-holds-barred approach to getting their demands met.

It is impossible to name an important housing campaign of the past five years which hasn’t had women at its centre.

We want to put together an event which draws all of this and as many of those women together as we can. Importantly, the aim won’t to be to moan, but to learn from and inspire each other so each woman attending can go away with a plan.

Speakers from Focus E15, Generation Rent, Black Activists Rising Against Cuts, the Radical Housing Network and Sweets Way Resists will tell all those attending about their campaigns and what successes they’ve had, and then lead workshops aimed at teaching participants more about how they themselves can affect change and stand up for their own housing rights.
