Still not sure I get your point.
Why are you trying so hard to specifically link defenders of women's rights to Reform?
Reform apparently has a lot of support (not sure why myself) so that must mean they are taking votes from all sorts of people with all sorts of beliefs.
Ultimately people vote for a party that most appeals to them, balancing the positives and the negatives in the way that makes sense to them as individuals.
Ultimately most people according to surveys want men to stay out of women's spaces. So of course there will be overlap, but also for example most people think vaccinations are a good thing so there will be people who believe in vaccinations who vote reform. So what?
