Yeah, nah.
There are feminist issues to do with lockdown, but lockdown itself is a public health initiative.
If you want to talk, OP, about how to ensure women can access DV services in lockdown, or the increase in workload for women who are mothers forced to work and homeschool simultaneously, or how an economic recovery needs to factor in the needs of women, that's cool.
If you just want to talk lockdown denialist nonsense and call it feminist, nope.
Lockdowns in my country have successfully suppressed or eliminated Covid, buying us time to support both life and economy until the vaccine comes along. Anyone trying to tell me women are worse off where I am compared to women in the UK right now, because lockdown, will get short shrift.
From the outside looking in, it seems to me that UK women are getting the worst of both worlds - restrictions without the success of actual lockdown. Ending up with all kinds of poor outcomes - health, financial, economic - while also paying a high cost on terms of lives lost, infections, ongoing disruptions, long Covid etc.
