I agree that's more important, but to me it's not more important than climate change or health etc so I wouldn't let this one issue of sex and gender be how I decide my voting
Vote how you want OP. It's good that you are questioning this and finding out a bit more. For me, womens rights are so important because if we don't have them, nothing else matters.
Look at the women living in Afghanistan at the moment. Would you be happy living as they do if you had a wonderful health system and big investment in climate science?
Or would you sacrifice that in order to be allowed to vote, to go to school, to drive a car, to go to the park unchaperoned by a male family member or just to be able to wear your own choice of clothes?
I think women in the western world have got so used to having rights that they are taking them for granted. It wasn't until 1991 marital rape became illegal in the UK. Not really that long ago. I'm not giving away my rights and that's why this is a fundamental issue for me. The other stuff is important too but I'm just prioritising.
If all the parties could stop trying to make laws around make believe and treat the protected characteristic of sex as seriously as it deserves then, as others have said, we can put this behind us and focus on the other important issues.
Everyone understands that if you don't see colour, you don't see racism.
Well the same applies here - if you don't see sex, you don't see sexism.
