When you've had to withstand the fucking onslaught of antisemitism that Jews in the UK, particularly Jewish women, have endured over the past few years, it kind of empowers you to also stand up for women's rights - because we've been relentlessly attacked, gaslighted, smeared, abused and misrepresented, so we're used to it... unfortunately.
See also Hadley Freeman as another example of a gender critical, kick-arse Jewish woman who is sick of all their shit (I am another one, but I'm not remotely famous so I don't count!)
