I disagree. Can you talk someone out of their religion? Their identity? Their belief system? In most cases, you cannot. Exceptions exist, certainly, but are not the norm in this regard. This could include those who are proudly racist, proudly misogynist, or take joy or satisfaction in the harm or pain of others. Are they evil? I think that distinction is a waste of time to be honest. All that matters is: “can you convince these people to vote differently?” If not, any time or effort you spend on them is wasted, and the evidence is robust a lot of these people will keep voting as they have, regardless of argument made.
