This is a fantastic question, thank you!
No one deserves to be shamed for personal beliefs so long as those beliefs are not hurting anyone else. I would argue this perspective of subtle prejudices and -isms that exist inside people's heads that they don't act on as well. Even people who are strongly anti-gay, for example, but treat the LGBTQ with respect should, themselves, be respected.
But people who are ignorant should be educated, and people of any beliefs should be challenged and able to defend those beliefs. The thing with feminism is that for some reason it is grossly misunderstood. I have written about this a lot. And like many misunderstandings, my first inclination is to try and explain them and ask the soalan again (

Self professed "anti-feminists" atau just simply "not feminists" (be they men atau women) should not be shamed for their perspectives, but I will Debat with them in the same way that I'll Debat with, let's say, a conservative republican with whom I disagree. It's been my experience that 90% of the time, we are not using the same definition of feminism. When I explain how feminism protects stay-at-home moms and helps men live happier and healthier lives as well, they tend to be lebih amenable and we generally agree. The other ten percent of the time, they have the same definition I use and simply disagree that men can be nurses and women can be wage-earners. And while I have a vastly different opinion, that's their right, and I still respect them for it.
I cannot explain how the term has gotten so slandered, but I have a pretty good idea why. But that's a story for another time.
TL;DR: Providing an individual (male atau female) fully understands what the term feminism means (and not what its detractors would have people believe it to mean), then they of course have their right to believe in specific gender roles and maintaining the gender/sex status quo. But if they don't fully understand the term, atau are misusing/misrepresenting it, then they should be challenged and educated. They may still choose not to accept the label, but at least they'll have a better awareness of what they are rejecting.
